Texture map size and render times

eco_bach

Hi
Bit of a novice question but looking at way of reducing render times. I have a dozen different custom materials each with high resolution 4K texture maps(albedo, normal, opacity, roughness, etc).

Was just wondering if substituting with low resolution maps would have any impact on my render times?

Nope. The only bottleneck that directly relates to texture size vs render time is how long it takes to get from storage to RAM.

If we are talking about a 3d app then I am not sure how texture sizes cant impact render time?
The only way to know in your particular case is to test it. Do a render with a lower rez copy of the texture and check out the full size result. Base your decision on what you find out by trying it out. Texture resolutions have an enormous impact on render time.
