This is a render for what exactly? I can't finish a client s scene beucase Octane randomly brake my materials, really, from nothing and I have several images to show this happening.
Image 1, I was with the materials set and I could see them all in material shading but when I pressed rendered...

Image 2, I done nothing, just got back to wireframe shading and got back to rendered shading:

Image 3,Here you can see the material shading showing all the materials working, but take a look at the material preview at the corner on the right.

Image 4, here I deleted a lot of extra geometry on the scene, but didnt deleted a single material, just for testing the GPU memor, but still have 2.500.000 polygons

Image 5, here I deleted lots of objects and materials on the scene, but the result was the same, even with less than a milion of polygons.

So, what the hell is this program, and above everything, what I will tell to my client now?
