Crazy Homeless Guy Posted June 16, 2007 Share Posted June 16, 2007 The VRAY frame buffer has a colors correction graph. first button on the left , bottom opens it up. 6th button from right enables it. I think I am calling it out properly. Why not BMP???? ...are you using this to show what the gamma corrected image will look like using by setting the curve to .6 and free or something like that? _________________ BMP is a dated file format, and not commonly used in graphics. there are other formats that offer better benefits. typical or common file formats are... tiff or targa for uncompressed jpeg and a few other for compressed exr or hdri for floating point Link to comment Share on other sites More sharing options...

BMP is a dated file format, and not commonly used in graphics. there are other formats that offer better benefits. Exactly on the gamma corrected image- Which other formats do you use. Sounds like a different topic. I'll check out the forum here for uses and advantages of the formats... cheers Link to comment Share on other sites More sharing options...
kwerch Posted June 16, 2007 Author Share Posted June 16, 2007 I saw the formats- I missed them. That reminds me...what is floating point? Link to comment Share on other sites More sharing options...

I'll check out the forum here for uses and advantages of the formats... cheers you should be using the latest release of vray, it is a free upgrade. in the latest release, they there is an srgb switch in the vray frame buffer, it is the last one in the bottom row. it will show you what your image looks like when gamma corrected. ...but back to what i said earlier, when you save your image from the view image dialog, use the gamma override, and key it to 2.2, then when you open your image in photoshop, the gamma will be correct, just like it is when you used 0.6 in the frame buffer. this is not a recommended way to work, but it will solve your problem for now.

kwerch Posted June 19, 2007 Author Share Posted June 19, 2007 Still at it! It appears that theGI enviornment does not save with the light maps. At least how I have it set up anyhow-When I do the light calc part I have things setup to see what the rough light calc is going to look like- When I render the same image using the light maps that I just created, I get the image but with none of the enviornment light. Maybe I just have something setup incorrectly. I do have the latest release of Vray with the RGB switch. It does not change the image as it does when I am doing the light calcs and using vray's color correction graph. cheers- Link to comment Share on other sites More sharing options...
kwerch Posted June 19, 2007 Author Share Posted June 19, 2007 I'm including two low res images-Neither rendered to the vrimg- The first, darker image is using the saved light cache map=Not what I was expecting The second, lighter image, is with irradiance and light cache createed as I go-no ref to a saved file-This is what I expected. I also did a partial render with the eviornment turned off and that is not the cause. I made sure to reset the maps before saving- What else could it be?
