I have a scene that was rendering fine using Maxwell

You mean using RC5 and MAX8? Are you sure you didn't use any older release for either one of them?

while it's generating the geometry using Maxwell RC5 as the render.

Try to hide some of the objects and rerender to see if there is a problem with one of them.

Hey there,
That also hapened to me yesterday and i think i the issue was that somehow a CMYK (it will show as RGBA on the selection screen of max when you are looking for the texture) managed to squeez in the sceene. After taking that and converting it to RGB it render fine. I hope that was it for me, no a 100% theory but it might be.

Does it crash with scanline too? Maybe you run out of RAM when launching render.

there is a conflict. we're experiencing the same problem with mental ray and final render in office. try loading the recent service pack for max 8.

I'm terribly sorry for reviving a 2-months old topic, but the same problem happens to me, only that I'm using Maxwell 1.0 (still, 3ds max 8 ). I can't figure out what can be wrong:

The scene rendered fine with maxwell, then after modelling more objects and modifying the scene, when I try to render (with the same material, a standard white material), max crashes (application error)...The scene renders without any problems with standard scanline or mental ray, but with maxwell it just crashes and it's very annoying.

This thing happened to the same initial objects (before adding more stuff to the scene), so I exported all the objects in a obj and imported them back in a blank scene and after that it rendered well...I didn't try to render the scene after I added just a few things, so I don't know if it's related to adding stuff, but I hardly doubt it.

Oh, I also have to mention that I once switched to mental ray, made a quick render, and then switched back to maxwell. But this crash happens all the time, every time I load the scene. Even rebooting and then opening the scene again won't work...Sorry for the long speech, but I must know the sollution to this as quickly as possible, for I'm under high pressure and I don't want to keep exporting and importing.

EDIT: I solved the problem, it turned out that I was rendering with mental ray's standard material . but still, the first time this happened all objects had mxm materials. Oh, and I'm rendering with physical sky and sun.
All the normals & vertices & polygons of the meshes are in their place.
