[Max] I need help! / Create a material not affected by light?

« Last post by aaouviz on 2025-09-01, 20:58:55 »

Hi all,

I have a bit of a strange situation: I need to create a material (as part of a multi-sub AND a layered material) which does not receive shadows/light.

Or, at least as little as possible.

I can't simply put the material on an object which doesn't receive light/cast shadows etc, as the material will be part of a multi-sub object where the rest of the materials possess normal lighting behavior.

I'm baking a unwrapped texture - one portion of the texture should appear to be without physical light interacting on it.

Making the material self-emissive isn't working quite right either.

The best result so far has been to give it the properties as shown below.

If this is the best I can do, so be it, but I'm wondering if there's anything else I'm missing?

Many thanks!

You guys were my knights in shining armor for sticking with Rhino + Vray for such a long time... shocked to see you here. Do you now use Corona too?

Nice work!

Hmm that is an interesting idea. Sounds like something an ai might be able to code quite well too.

Yeah, I have built a parser in the past but its not fun, lots of regex. But certainly possible with AI and testing.

Cool thing about fbx is it has so much data you can lots with it, like build a bridge between 3dsmax/c4d, or max to blender etc since all its doing is looking at the data tree and then putting it into a json file, then you can rewire it on the other end so if its using a coronacolor in software A, change it to this node in software B, then copy the values etc. Simple concept, but lots of things to take into consideration.

Ideally there would be a full scene memory report available from corona like the texture memory useage csv, but for materials and geometry.

Thats a good idea.

In the mean time I suppose the only thing I can think of is the old 50/50 way (remove 50%, hit render), do it again until the speed jumps up significantly, then you know which chunk to investigate.

Another idea which could give you more info (for geometry, and other info too), export one of those chunks as fbx (ascii not binary), then open the fbx with notepad. This will give you a tonne of info about the objects and its data but you would probably need a custom parser to get the data you want sufficiently, unless you dont mind scrolling though millions float values lol.

Hmm that is an interesting idea. Sounds like something an ai might be able to code quite well too.

But yes the whole 50/50 approach is what ive ended up having to do.

Ohh sorry yeah I meant .mat Libraries
What a pitty, since I come from V-Ray there are lots of things that Im missing, this is driving me nuts, even turning off rendering or showing as text.

[Max] I need help! / Cryptomatte layers all grey instead of pure white

« Last post by Jpjapers on 2025-09-01, 17:22:58 »

Im having a really weird issue with cryptomatte in photoshop from a CXR and the EXR.io plugin.
Every single mask layer is greyscale instead of pure white meaning whe used as masks, the resulting layer is semi transparent.
I have no idea whats causing this.

Any ideas? Im completely stuck without it.

[Max] I need help! / Re: Bloom/Glare in CIE doesnt work with lightmix?

Ok thanks, Seems a little misleading to name the pass 'Bloom & Glare interactive'

General CG Discussion / Re: Help with Max scripting

« Last post by aaouviz on 2025-09-01, 17:00:06 »

Any idea how I can change the "randomSeed" value of a CoronaMultiMap (or any node) with a script?

Ideally I can +1 the existing value, or toggle between 0/1.

Any help MUCH appreciated :)

You will need to bake the lightmix adjustments and re render few passes to update the Bloom Passes. I have logged this in our system for our devs to see if this can be improved.

Gallery / Interior Visualization: Elegant. Sculptural. Dubai

Location: Dubai, UAE
Visualization: Render Vision

In Dubai, demand shapes design. The city attracts a discerning, affluent audience — and interiors respond accordingly. Clean architecture, grand views, and expressive decor come together to meet elevated expectations. These spaces are crafted not just to impress, but to reflect refined lifestyles through quality, proportion, and atmosphere. 🌊 🎨📐
Our 3D rendering captures this philosophy. We translated the interior into a series of renders that highlight its spacious layout, rich textures, and elegant palette of gold, beige, white, and black. Carefully selected accessories — sculptural lighting, accent art pieces, and curved forms — bring personality and rhythm to each scene.
From the soft morning light streaming through full-height glazing to the subtle sheen of metallic surfaces, every detail was rendered to evoke presence and sophistication. A calm, elevated aesthetic — visualized with precision. 💎 ✨
