  1. Okay, that's helpful then. What do you mean by not animated? Do you mean they are not visible to the camera? I don't know your rendering setup, but you have to take in to account that although something might not be directly visible in the frame, it might be visible in a reflection, so max still loads it in. So something like a tree leaf, which might have a glossy reflection value, and potentially thousands of leaves at different angles, if one leaf needs to reflect an object that is not visible, VRay loads it in. If you hide objects that aren't visible, they won't be loaded so perhaps you can hide some things to speed it up?
  2. Unfortunately there is not a way. By the sound of it you have just the one machine to render on........50 extra hours is a lot when you only have one machine. But if you think about it, 3dsmax has to figure out what it needs to render for each frame, which actually saves you time and probably RAM because if it loaded the entire file at the start, that might take up all the RAM you have and the file would crash when it renders. I think your only solution is to have more machines rendering. Maybe try a render farm online. There are many.
  3. Thanks Nicolai. It's an option for sure but i always try and do as little post as possible and try and be technically correct. It's highly likely that this sort of thing will have to be tweaked in post so I will use the shadow pass where necessary. thank you.
  4. Sounds very similar to my setup. I agree that not all dichroic glasses change the shadow colour, but the one I've been spec'd clearly does! I think I'll stick to the "cheat" that I've got as it looks very convincing. I'm not sure mapping the exit colour would work, as it might make the glass appear different as i think you'd have to lower the max depth to get the colour to show and that would make the diffuse colour wrong too. Mapping the shadow colour a material gives would be what I want! I love having these little gems to figure out. Although my brain is hurting having been on holiday for a week. It's tough to jump straight back in to these kind of problems! thanks for taking a look mate. Much obliged.
  5. Thanks Chris. Just FYI, I have faked it by duplicating the object and applying a glass with a purple tone so the shadows are purple. Hidden it from rendering, and made the blue one not cast shadows. I hope that makes sense. But i'd be interested in seeing if it's somehow possible to do it all in one material, although i don't think that's possible in VRay. Good luck pal!
  6. Hi all, It's been a while since i've posted on here but I have a question regarding a certain type of glass. Dichroic to be specific. check out some examples here. http://lmgtfy.com/?q=architectural+dichroic+glass It seems in the material sample I have been sent that the shadow colour is different from the diffuse colour and n some examples in a google search ths s also the case. I have no problem creating it to look correct for diffuse, reflection etc, but a different shadow colour I cannot seem to do. It might have to be a post production job. I was wondering if anyone's had to create a similar glass material that has a different shadow colour to its diffuse colour. Lets say cyan/blue diffuse but magenta/purple shadows? Thanks in advance.
  7. Maybe you could explain your scene in a bit more detail. Are you using a sky dome? Or just background image, or even a HRDI. Is it an external scene, or an internal one looking through a window? Steps to try....... 1. Make sure your glass is affecting Alpha in the material. 2. If you are using a dome light, tell it not to affect the Alpha in the Dome Light rollout when the light is selected. 3. If you have a skydome, select it and right click on it. Choose VRay Properties and set it's alpha contribution to -1.0. This will still be visible in the render, but not in the Alpha channel. I hope one of these fixes your issue. If not, post again!
  8. Hello, Welcome to the forum. It's been a while since i posted but hopefully I can assist you. It sounds like your blue glass is okay and it's the refective panels you are struggling with? Without seeing your render, or material setups i'd hazrd a guess and suggest you try changing the reflection colour of your material to blue.... Those sunglasses have no translucency at all, so keep your refraction value black. I hope that helps.
  9. If you haven't got gamma 2.2 setup I'd suggest that to boost the lighting right off the bat. Can you post your render settings for us to actually see. not these test settings, but the final render settings. We can probably pin point the settings to increase if we can see them
  10. It would help to see the material and the object you are talking about. But going by what you said you could try telling the plane not to be visible to reflections in the object properties. I assume in your rendering the bright white blob is the problematic thing you are trying to remove?
  11. Hi Ruan, There are quite a few simple things that you need to do to improve your renders.Look at your models and improve them. You can have the best lighting ever created, but your renders won't look photo real, without the models looking real. Make sure your textures are setup correctly and realistically too. Use the VRay camera or 3dsmax camera like a real camera. Setup the exposure properly and use it like you would a real one. If you improve your photography knowledge in the real world, and bring that to your renders you should see a vast improvement. There are plenty of tutorials online about photo-realistic lighting and rendering so search around and invest your time in your efforts to improve. Just asking isn't the answer, you'll need a lot of hard graft to get there but if you apply what happens in the real world in to your renders, they can only improve. Good luck!
  12. Hi peeps. Here is a link to my maxfile. Save it on your system. I saved mine in to the 3dsmax scenes folder to keep things tidy. Custom VRay Material Slot.max Do the following to load it in. In the material editor window (I'm old school so still use the compact mode) press O to open the option window. In the Custom Sample Object click on the button and load in the maxfile you saved. Tick Load Camera and/or Lights as this will use the lights and camera in the maxfile. Then click apply. Now on a material slot you need to change the sample type to custom and the slot will change to the custom one from the maxfile. This is the top button along the side of the material slots that looks like a sphere. Hold your mouse down on to it and change it to the question mark. You can change the lighting/exposure of the sample slot or the custom shape by opening the Custom VRay Material Slot.max and changing the camera exposure or the object. Just make sure it doesn't go outside of the Viewport safety area, the yellow square around the viewport. I hope it's of use to some! It's by no means brilliant and i have since stopped using it to be honest. Hopefully Chaos will implement a version like Corona does, but i fear that's a long way off! If you ass a background in to my file, when you change the diffuse colour, it changes the background too which is a bit annoying!
  13. Something with no compression is best like a .tga or .tiff. I wouldn't use a PDF to print from. .Jpg is also okay for most print purposes if you don't compress it. So leave that on it's highest setting when saving. If you can .exr give you the best files to save out from Max. If you know how to utilize the benefits in Post. Otherwise go for a .tga or .tiff again as these can be either 32-bit or 16-bit depending on your needs.
  14. After posting this I actually managed to get a Custom material slot working using VRay. It works quite well but I didn't spend long doing it so need to test a few things out. Not sure it works quite the same. I need to check out the one you linked to Juraj. Thanks for that. I'm surprised it's not been mentioned before on here, I haven't checked the chaos for for such requests. I can't be the first surely. I will check though and if it's not been suggested I will be sure to. It would be great if when you change Max's renderer to VRay, the material editor automatically loaded in VRay rendered material samples with GI etc. It would help a lot. I will definitely continue using my custom one though. I think it will work very well with some tweaking, I just need the time!
  15. Hi all. I've dipped in to Corona over the last couple of days and i must say i like it! Planning on converting a work interior from VRay to Corona to see how Corona looks on an actual project. Anyway, I love the way corona displays materials in the material editor, why doesn't VRay do this!? I've Google searched to see if it's possible to do something similar using a customized material editor file to replicate this with VRay but it seems that although you can create a custom material editor slot with your own shape and lighting using standard lights, there is no support for VRay lights, even if VRay is set as your renderer. I hope this is something they will implement in the next release. But I expect updates to slow down since they've launched VRay for other software packages now. I expect they'll be ironing out any problems with those for a bit. Your thoughts peeps.....
