Very nice render, very good work with shaders...

awesome render
hope you don't mind i stick it in our gallery ?

Sure

I can't load any more texture (...maximum number of 32bpp textures...)

How many textures are you loading?

We are talking about 80 textures in C4D. In octane I get rid of 10 of them.
Again Paul Russam's church, now with stained glass.

So are you saying that 70 textures is the limit in Octane? If so, is this a hard numeric limit? Or is this a limit because of GPU memory?

There is a limit on the amount of image textures, this is a hardware constraint.
However, you may use as many instances of the same image texture,
and you can create as much materials as you like, and you have no limits on procedurals.

In case this is not enough, you can always stich together some textures and modify UV maps to use one larger texture.
we're working on improving this.

abstrax:
Thank you again.
With C4D exporter I have no more problems with smoothing groups.
Also I noticed a great impromvement of specular materials. I dont understand yet why but I will do more tests.

I want to make sure I understand this correctly. You are saying it is a hardware limit, that Octane itself does not limit the number of image textures. Correct? I am assuming then that CUDA is limited, and any GPU based renderer that uses CUDA will have this issue.
