Rendering with highRes-textures extremely slow and unstable

[verstaerkermusic]

i have a very simple scene with 1 object that uses 4 8k textures. It takes quite long until a render starts. Roughly 2 minutes.
Maya calculates something on 1 core - this takes easily 2 minutes. Then the render starts.
It looks like RPR is reading the texture file each time a render starts.
Renderers like Renderman or Arnold use special converted mipmap-textures to optimize reading speed of textures. maybe this could be implemented too.

Hi,

On the first render of the scene it will take longer then normal, this is becuase its caching out the textures to the Drive. on the 2nd render it should be faster then the first render.

Also its possible that there are unsupported Maya nodes in the material graph. is it possible you can share the scene with the maps ?

Hi
yes i'm aware that the first render takes longer... but also the second, and tenth takes very long.
I'll prepare a scene with maps later today.
