Hello and thanks for your time,
I am using a 6000X6000px JPEG file with a noise texture on it but with a very small grain size, so it looks essentially like sand grains. The high res was used to capture the fine grain detail. I need to apply this evenly over a plane with a little bit of form on it. The idea is to apply a grainy like sand bump over the plane and distribute it evenly over the surface with explicit mapping and for smooth animations.
I used to use a procedural noise map with a very fine grain size but I found that it did not map out well over slightly distorted plane (blotchy, and uneven)
With the JPEG as my bump map source, the render times have gone up by 50%. Sampling sizes are the same.
I thought rendering time should have sped up with a Bitmap for a bump since its a pre-determined size and the sampling does not have to anti-alias as hard as with a procedural.
any ideas?
