[Max] Bug Reporting / IPR render in new Corona 5 memory leak

« on: 2019-11-26, 17:05:43 »

Hi guys, today I have time and I want to test the new corona 5 demo version on production project, it is very very simple scene have 4-5 materials without displacement or crazy stuff, but after some time IPR used my all memory and max crashed or my pc crashed, tried multiple times same result

[Max] I need help! / Lanczos filter

I look in the image filter and I can't find Lanczos filter, neither Mitchell or Gauss.
I like the Lanczos it 'the best, is there way to get ?

[Max] I need help! / opacity cut out problem

« on: 2017-01-19, 11:24:10 »

I  have two surfaces one on each other the top one is slightly moved up.
I use two material different with displacement that's why layered material is no use.
When  apply material with opacity map on the top surface the opacity don't make the material completely opaque cut out, the problem is on that material I turned on refraction, without refraction is ok.
How to solve this?
Is refraction settings override opacity?
I tried to put the same map in refraction color, and opacity color no success.
I only success when I turned thin refraction or IOR 1 but I need IOR to be 1.33 to refract to not be air :D

[Max] I need help! / Corona light sample problem

« on: 2017-01-12, 19:23:20 »

I want to make brush metal I put normal map on the bump slot with very fine thin lines.
When I render with lighting form HDR everything OK, but when I render with corona light sphere the lines of the grooves are pixelate and there is noise.
I tried to blur the normal map, increase corona light, increase light samples, increase GI vs AA no success.
Or there is also noise when I render with HDR but I don't see clearly because it is masked with the other parts that reflect the HDR.
I attach the normal if there is something wrong with it.

[Max] I need help! / Subsurface dark color

« on: 2016-12-26, 14:49:51 »

I put the same color in the scatter color slot like in the diffuse before and turn on the opacity to zero to test the subsurface scatter and I get darker color then before when I render only the diffuse without scattering, other settings I don't change from the default CoronaMtl.
I need to get the same color of the scattering like in diffuse because I want to plug texture in the scatter color slot. I try form eye to correct the texture to make more bright but then the white parts  became strange the white it come like iridescence.
Are there some settings that I missed?

[Max] I need help! / Light intensity relate with size

« on: 2016-12-20, 17:17:21 »

 Why when I increase radius of the light the intensity also increase and get brighter in the room. I put the intensity in lux, lumen that mean all light from it is that put with the number, why is it increase when I increase light size
