[Max] I need help! / Re: Cannot mask a material with an Xref with CMask

« on: 2023-03-23, 19:57:33 »

I got it to work, but I had to open up the Xref itself and change the Gbuffer ID there instead of doing it in the slate editor within the main file.

I'm trying to create a monchrome mask of a material within an Xref that is then plugged into a subobject material. I have the G-buffer ID set to 9 in the material, and the CMask setting, but I'm still not getting a mask. Is there anything else I could be doing wrong?

Thank you everyone. 'Base tail' was what I was looking for but is a bit hidden as far as features within the Physical Material options.

On these chair by Sanaa, the chrome has a subtle white cloudy appearance. What would be the best way to achieve this? I don't think it's a result of roughness, but could be wrong.

[Max] I need help! / Re: Corona Curvature map not behaving like I would expect

« on: 2022-12-05, 18:25:03 »

It's been my understanding that Corona Curvature map can be used like the AO map, but it looks directly at the mesh curvature instead of emitting beams from the mesh and seeing when they intersect it.

So I'm trying to make some steel darker at the concave portions of this object, and I have the curvature map plugged into my material with a red color plugged into the Concave Color input. The max distance is set to 1/8" and the other settings are default. I can see the steel being red right up to the point when the actual curvature begins, then it appears to become lighter at the portion that begins to curve. Is there a way to make it shaded consistently at the curve? The editable poly has no borders, so I don't think it's an issue with the geometry.

Is the model an import or something you've modelled?

It's something I modeled. However, I modeled it in Rhino and imported it into 3dsMax and cleaned up the geometry.

I get a smoother result using AO without the break in shading. The top image is AO and bottom is Curvature

Gallery / Two-Fold Chair & Table

« on: 2022-12-05, 17:13:38 »

This is a set of furniture I designed as part of a larger conceptual project that I'm working on in Nashville, Tennessee.

I call them Two-Fold Table & Chair because the idea is to fabricate these pieces from folding a sheet of stainless steel using two folding operations.

The lighting is from a PG Skies HDRI. Other objects and textures used are from Cero Cuadrado (link below), Megascans, Nouvelle Mesure, 3D Sky, The Boundary, 3D Collective, and CG Trader.

[Max] I need help! / [solved] What is the correct way to model liquid in a glass vessel?

« on: 2022-11-21, 15:14:34 »

If I have a glass vase that is ~1/8" thick, should the liquid (water in this case) object be modeled such that it's out walls (except for the top surface) fall within the 1/8" wall thickness of the vase? It's kind of hard to describe, so I'm willing to provide a sketch, but I've always been curious about if there is a correct practice here.

Are you using the depth map to define the haze in post processing?

Hi John! Yep, using the https://support.chaos.com/requests/new link will let you describe the situation and send in the scene or other attachments (privately, so only for us to look at and only for bugfixing purposes). TY!

Cool, I'll send it now. BTW, I'm not even sure Corona is an issue here.

Would need to know some history - was this previously saved in an earlier version of Max? Of Corona? If so, which versions? Were any changes made or just a straight open-resave? Does it happen in non-Corona scenes? Is it every scene or just this one? Can you send the scene in? (https://support.chaos.com/requests/new )

Can I shoot you the scene via the link for you to take a look?

I had a max file around 240mb, and suddenly I see it's jumped up to just under 1GB. Are there any ideas on what may be causing this? I didn't add any geometry or textures to the scene that would cause such a big jump in file size.

Does anyone have advice on how to create soft, overcast lighting with the cloud parameters? I'd like to recreate the lighting effects from a favorite HDRI of mine (or get close), but I keep getting some pretty strong direct sun shadows.

You control sun shadow sharpness w/ Sun Size parameter. From 0.01 (sharp) to 64 (soft).
With Clouds, control is enabled by turning on "Apply shadows from clouds".

Is the 'apply shadows from clouds' checkbox located in the Corona Sky component?
