[Max] Feature Requests / Corona Layered Material - Wrap to Underlying

« on: 2021-09-23, 06:18:19 »

In the context of the Corona Layered Material, why does it make sense for Layer 1 to inherit displacement information from the base layer, but not bump information?

It would be great if there were a way to control the influence of bump information from an underlying layer (e.g. base material) on a subsequent layer (e.g. Layer 1).

The CoronaPhysicalMtl base bump and clearcoat bump provide a (sort of) paradigm to think about how this functionality might work.

General CG Discussion / Arrange / Distribute Objects

« on: 2021-09-15, 08:01:38 »

Look all over, but cannot find a script that evenly distributes a selection of objects in n-rows / n-columns. MCG-Arrange accomplished this task, but is not functional in 3ds Max 2020.

It's very surprising to me that such a script does not exist(?)

General CG Discussion / Project Management Tools - Project / Time Tracking?

« on: 2021-09-13, 04:02:33 »

I really need a better, unified method for tracking multiple projects, time (hrs, days, wks) attributed to a project, miscellaneous costs (assets, software, rendering, etc.) associated with a project, etc.

I imagine others on this forum achieve this type of project management through some toolset, software, website, etc.

What are some good options for individual contractors?

[Max] I need help! / Corona Bitmap (Mapping) vs. UVW Xform modifier

« on: 2021-09-12, 19:51:48 »

Corona Bitmap and 3ds Max bitmap scale UV tiling from the center of the texture space while the UVW Xform modifier scales UV tiling from left to right.

This feels like a typical development oversight from Autodesk, but I'm wondering if there is a way to align the functionality of these two (three) implementations(?)

Right now, the only way to replicate the UVW Xform modifier in the mapping settings of a Corona Bitmap is to offset the UV tiles, but this can get really complicated for arbitrary offsets.

[Max] Feature Requests / Corona BumpConverter Texmap - Additional Bump

« on: 2021-09-02, 07:25:47 »

It would be nice to have an 'additional bump' slot for the Corona BumpConverter Texmap - as is true for Corona Normal Texmap.

[Max] I need help! / Fluorescent Light Bulb Material

« on: 2021-08-31, 03:29:29 »

I think one of the mods posted a comparer (side-by-side) of a render of a fluorescent light bulb material, perhaps in the context of the release of the CoronaPhysicalMtl; a translucent milky white with a clear coat(?)

I need to create a material like that, but cannot find the post I'm referring to. Can anyone advise?

General CG Discussion / 3ds Max Slate Material Editor - Node UI

« on: 2021-08-24, 02:06:18 »

Selected nodes can be selected to 'show in active viewport' in the Slate Material Editor. Activating this feature draws a red overlay on the active node (see attached).

Is there a way to disable (i.e. 'hide in active viewport') multiple nodes at once?

[Max] Resolved Bugs / CoronaPhysicalMtl - Displace -> CoronaDisplacementMod

« on: 2021-08-23, 23:34:13 »

If the CoronaPhysicalMtl > Displace (Min level, Max level) is set to 0, then the CoronaDisplacementMod cannot set the surface displacement.

It would be better if the Corona DisplacementMod itself set the displacement if the CoronaPhysicalMtl is set to 0.

[Max] Feature Requests / Volumetric Fog

« on: 2021-08-23, 05:59:26 »

Corona Renderer needs a vastly improved workflow for working with, what in Unreal Engine might be called, Exponential Height Fog; volumetric fog effects for interior and exterior rendering.

Corona Renderer, even with the Fast Preview Denoiser, is too slow to render these effects, so much so that it interferes with artistic experimentation, look dev, etc.

A cheaper approximation could be appropriate, with an option to enable physical accuracy (e.g. caustics), but altogether there needs to be a better method for this that doesn't require vastly more expensive hardware to render on.

General CG Discussion / OSL Shader: Expose Bitmap Filtering / Interpolation

I would like to add some code to an OSL shader I am using to expose Filtering / Interpolation options like in the Corona Bitmap. Any suggestions?

[Max] I need help! / Corona Normal Map vs. Bitmap Random Tiling OSL

« on: 2021-06-27, 03:29:43 »

Normal maps loaded via the Bitmap Random Tiling OSL shader do not work with Corona Normal Texmap in 3ds Max 2020.

The following Bitmap Random Tiling OSL shader parameters do not affect normal map shading / are not modified by Coronal Normal Texmap
1. Flip green
2. Flip red
3. Normal map

[Max] I need help! / CoronaDisplacementMod

« on: 2021-06-11, 23:26:12 »

Corona Displacement Mod is not displacing surfaces unless the 'Get from material' material has non-zero displacement values for the 'min level' or 'max level'(?)

[Max] Feature Requests / Negative Filmic Shadows?

« on: 2021-06-10, 21:35:34 »

With tonemapping being under development, this may be a pointless suggestion / question, but I was wondering if we could get negative contrast or negative film shadows?

It would be a good way to *remove* contrast from an image that is over-contrasted, darkened. I think this would be useful, especially in combination with filmic LUTs.

Obviously we could use curves for this, to some extent, but I'd like to be able to target those contrasty areas using the filmic shadows 'algorithm'.
