So Slow

[glorybound]

Thanks, guys. I am not happy with it, but it's probably because I have been staring at it since Sunday.

I'm actually surprised by this; it doesn't make much sense. Is that the case even if you switch the default geometry type to "static"?

Not sure about the latter - never messed with it. I have just noticed that the rendering stages prior to the LC being generated are quicker with everything collapsed.

ahh yes, that makes sense.. since vray has to prep all the geometry for rendering at that stage, so its got an easier job if everything is collapsed. i assumed people were suggesting the actual rendering bit should go faster.

So I was looking at the scene again, and I have two questions:

1) Filtering of bump textures is practically disabled (texture blur is at 0.01); this causes a lot of inherent noise in the scene (the walls, ceiling etc) that V-Ray is trying to resolve in vain. Is there a specific reason for that? It might make sense to decrease filtering a bit, maybe 0.5 or 0.2, but 0.01 is way too low.
2) You do know that a Color Correction texture has no effect on bump mapping, right? I see that all your bump textures are piped through a Color Correction node that doesn't really do anything - it's just empty code that is executed. Not too important for this scene, but given that the Color Correction texture is very very slow in older versions of 3ds Max (it was fixed in 2015), it might be a factor.

Hey Vlado, are there recommendations for what to use instead of the Color Correction node if working in older versions of max? I'm guessing it's just to fix the texture in Photoshop

[glorybound]

I didn't know that the color correction doesn't work on bump textures. Does it already remove the color?
For the blur, I think cleaner script is doing that. It's one of those automatic things it says needs to be fixed. I'll keep an eye on that.

an image used in the bump slot only considers the value of the pixels, not the hue or saturation. doesnt matter if there is colour in the image.
