[Max] Resolved Bugs / CoronaVolumeMtl: Transparency Issue

« on: 2022-07-09, 21:50:34 »

(This is on 3ds Max 2023 with Corona 8.2)

I'm using a cylinder with a volume material to act as a "container" of sorts for some noise clouds.
At first when I ran into a transparency problem involving the cylinder geometry itself appearing as a silhouette in the render, I did the EnviroDistance fix as listed here (https://support.chaos.com/hc/en-us/articles/4528311915025-Known-bugs-and-limitations) to workaround the problem; iirc it was 1000cm prior, so I set it to 500,000cm after several adjustments.
 
It seems to have mostly solved the issue in terms of the BEAUTY & CESSENTIAL_Volumetrics render elements, however the Alpha render element itself still shows that it remains to be an issue.
Here's the scene & images pertaining to said render elements.

[Max] Feature Requests / A map similar to the VRayHairInfoTex map for hair tip transparency

« on: 2019-11-27, 21:49:15 »

I've tried using both the Gradient and Gradient Ramp maps in the Opacity map slot of the CoronaHairMtl, however neither seem to give me the result I want. The Falloff map also doesn't seem to properly handle this. So with tht being said, having a map that can control the transparency of the hair strands like the VRayHairInfoText map could be very helpful in my opinion.

[Max] Feature Requests / Parallax mapping option as an alternative for displacement

« on: 2019-11-06, 00:39:25 »

I have used the parallax feature Marmoset Toolbag 3 has and it's honestly pretty great imo for saving a lot of time compared to displacement, whilst still getting the same result when also using a normal map with it. If this isn't too much to ask, I would also to see this supported with Corona as a compromise for those who like the pros of displacement but don't want to deal with any inconvenient issues it may bring and/or just want to save more time. I remember several months back when I saw a message by Ondra 6 years ago saying that "This is too big fake suitable for games, but not for realistic renderer", and while it's true that it's usually good for games, that doesn't necessarily devalue it's efficiency in both games and high-end CG renders imo. I personally don't think that should be a reason to *not* include it, but that's just what I think. Either way, this renderer is pretty great, which is why I think (if it aint too much) it would be great to have both displacement and parallax options for the user.
