Eroor - "UNHANDLED EXEPTION"

[yuckuJackD]

Hi,

i'm using 3DS MAX 9 with Vray 1.5 RC3. For first time i see this error (see picture as attachment). The scene is created with materials tested in previous jobs exept one - water in the swimming pool, but i removed it and - the same problem.

Any one has any ideas how to deal with this?

10x for assistance and sorry for my english

[Stephen Thomas]

Why are you using RC3 and not the final version of Vray?

I red the other posts about this error, but didn't find a decision (admin don't delete this, i've red the rules )

[Nic H]

do you have displacement on?

[leninsankaralingam]

can you send the details of your hardware rendering machine

Hi

 

I do get such errors for which i m giving u some guesses:

 

1. turn on the vray frame buffer

2. increase the amount of memory (MB) in system rollout of vray renderer setting about half of the amount of installed system ram if you are using 32-bit max dont increase it more than 1000 MB.

 

3. Check any transparent "standard" material use vray material instead.

 

4. if there are absolute identical objects in the scene then copy them again with instances "on" (only if they are not instanced)

 

5. Use Light cache as the secondary GI engine. It will increase the light intensity a little bit in the darker areas and will decrease the rendering time.

 

6. Check if there are any double polygons working in the scene and visible to camera.

 

If this helps you i will be greatly happy

Harware - attached screenshot of dxdiag

intel core duo quad cpu - 2.66 ghz

ram - 3 GB

Video - ati 4800 (512)

 

manish_mv - most of your suppositions i've already tried

i aways use Frame bufferer

No "standart" material at all

instances used where possible

i aways use Light cashe: for good quality - 1000 for fast rend 600 (subdiv)

about double poligons i belive there are not (checked)

now i'm waiting to see what will happen when i increase the amount of memory

 

thanks alot to all of you

i hope to solve that problem soon

[yuckuJackD]

That's it!

nicnic - you were right too much/many (not sure the gramattic) displacement

for now it's all right (still rendering)

 

thanks again to all. You guys are cool

Displacement can be tricky to get right... It depends on what you are doing, but I try to use 2D displacement for as many things as possible. It uses far less memory than 3D. You have to just play with the settings to see what works and still gets the right look.

 

2D mapping works pretty well for most things. Its big downfall is that it doesnt wrap the edges of objects well. But for things like carpet, grass, sand dunes, paneled walls, water, etc, it works great.

 

3D mapping is harder to get to work without crashing. I use this for, say, basket weaving, and things like that. The biggest thing that I had to work out was a function on 3D called Edge Length, a value that you can enter in pixels. The thing about this is that the pixel value is based on your final sized rendering. If you try to render something at 800x600 with the default 4 pixel Edge Length it may render find and look good. But if you move up in size to 4000x3000, it may crash, because that Edge Length is still set at 4 pixels. If you increase that Length (maybe even up to 24 or 32) you can get the same look on a larger render.

 

At one point I had an ocean that I was doing in 3D mapping, and I was constantly switching back and forth between 1200px wide for tests and 6000px wide for client updates... If I didnt remember to change the edge length the render would crash. It's just something to keep in mind when messing with displacement.

mfured20, thanks for your advice, i'll play width displacement 3d/2d in the weekend to get the right idea how to use it proper

You are right that i used 3d mapping for disp, but that's because i had many visible edges.

I'll attach one rend (no photoshop on it yet) to show you my scene. It's just a part visible, there will be other rends showing the whole scene from different views. And i'll try to make a movie. Possibly there I'll have problems too, but i hope everithing will be OK

 

I'll be happy to hear your reviews about this rend.

 

Thanks again

Is this with all of your displacement on? Most of my critiques are with just a few design things that will help as you go along. Since most people never actually look at a space from an aerial perspective, I find most images like this one only useful for design critiques.

 

With the pool: I assume that there is a hot tub up on top, with a little spillway coming down into the main pool. If that is the case, I would change up that solid blue wall at least a little bit; you could add a mosaic, or maybe put in some little steps and things of that nature just to break up the big blue monotony.

 

You should put some kind of caps onto the tops of your stone walls; they almost never have joint lines on the top. Try just a box or a chamferbox with some subdivisions and a noise modifier on it, thats how I do mine. Make sure to get the ones under the railing too.

 

I would put some foliage on the left hand side of the house, between you and the neighbor. This will help give the space a sense of privacy.

 

About the glass windows: they look really reflective. It may just be the camera angle, but I would drop the reflection a touch. Also, if there is light inside the structure, it will help decrease the reflection and let us see a little more of what is inside. I assume you have Affect Shadows on, but turn it on if you dont. Or add a couple of lights inside to help brighten things up.

 

Grass: this is a nice repeatable texture, I like it a lot. From eye level it will work fine. Depending on what kind of rendering times you want, I have used both displacement and vrayfur together on the same object to make great looking grass; There is a thread on here somewhere [or maybe it was on chaosgroup] about running grass in this manner. The guy used three different vrayfur modifiers on a single plane, each with only light scattering and different lengths / bends, etc. He also applied low displacement to the plane itself to fill in the gaps between blades. The effect was great, and its not that much more time consuming. I think that working something special for the grass would be a nice touch, since you have done so much with the green roofs.

 

I like the building itself. Something you might think about doing would be to have some sliding glass door [or nanawalls] right above the upper pool area [hottub?] so that you can go straight from the inside into the pool. The opportunity is there, it would be a shame to let it go to waste.

 

Overall the lighting has a nice diffuse evening look, and I like the general effect. I would suggest as you go forward you try a nighttime view from down at the corner of the pool looking up toward the building so you get the reflection of the glowing interior in the water. Also a view from up above looking back toward where the camera is now might be nice, just to show how the home blends seamlessly into the landscape.

 

let me know how this goes.

Thanks for your review, mfured20.

You gave me some good ideas (about the night rend )

The water in the pool - I lost whole day in tests changing materials but there was no result so I'm tired (in any other job i'll make it better )

In the scene there is no displacement at allany more. Because of the error I reduced bump and shitched off the displace.

good idea about the caps, but the architect doesen't like it (I'm the guy who makes the 3d's just like hi imagine the buiding )

as i said i'll make a movie and that mean 3 or 4 days to stay without PC while rendering. I plan to start rendering at friday night, so till thuesday i'll be innactive here, and then - upload the results

Thanks again for review.
