Hi all What’s the difference between setting the blur to 0 (well 0.1 is lowest it can go), and changing filtering to None?

When Blur is set to 0.1 3DSmax still filters the image with very small amount while when Filtering is none it doesn’t apply any filtering.

:- ) Let me rephrase my question then. How does each influence render times, the sampler etc, and which one is the “recommended” option?

sharper texture = longer render time as its more stress on the sampler. But imo it looks better. Blurrier texture is softer and less noise faster render time, but looks blurry. You pick what you need based on time frames and quality you are after.

If you need sharp textures, the elliptical filtering in VRayHDRI might be a better choice, leaving both the filter blur and the filtering setting at their defaults. Best regards, Vlado

Vlaod, can elliptical filtering be added to V-Ray for maya? I did a quick search and check in Maya’s file node, didn’t see elliptical filtering as an option there.

I have done some test speed wise in 2 version with checker and with real world materials (10 images for each version), and also put the sample rate and raw renders for download in this page. http://mohseni.info/map-filter-comparison/ 1.Bicubic (VRayHDRI) 2.Bilinear (VRayHDRI) 3.Biquadratic (VRay…

Thanks that is some interesting info! On the 2nd chart however I think there’s a typo, the 1st bar and the last has the same titel?

when I have been playing with vrayhdri I have found a parameter that called FilterSharpness but I have test it and there was no visible effect on samplerate map. so I was confused and just test with default of FilterSharpness = 4.0
