OctaneRender® for 3ds max® v2019.1.5 - 8.19

[jimho]

Regard to the material convertion,

In 3dsmax there are two type of image both work with opaque channel mapping
1, an image in png type with a transparent background, which will be correctly translated into alpha image, the convertion will be correct.
2,3dsmax allow black-white jpeg as the opaque mapping, but this type of image is considered as greyscale image instead of alpha image in octane,
after translation, though the jpeg file name is the correct, octane will not find them (there is no jpg type selection for alpha image) and the opaque mapping will be actually lost. so there is always materials mistakenly converted when opaque channel is using a black background jpg,
Manually we can fix it, but unfortunatly we users may not realize which material is correctly converted which is not.
All versions have this issue.

using an RTX2070 441.28 on windows 10 on an MSI laptop ge75 raider 9sf (64G RAM, 5TBHDD)

Hi nildoe,
thanks, I cannot replicate the issue, could you try using 442.19?

Hi Paride..any word on this issue? i need the sun to work for a project

[nildoe]

I dont know if this issue is fixed on other later releases.. but i think i found a bug with shadow catcher feature...

I have a an animated light in my scene set to light only on light pass2.. I have object on light pass2 and this light works OK... but in the same scene I have a wall that suppose to catch light and shadow from HDRI... and I excluded it for light pass2.. still the wall catches the shadow coming from the objects near it...and the shadows are coming from this animated light... is that normal behaviour??
