Your setup is very similar to mine, with the exception of the label and glass roughness additions in the glass base roughness slot. I'm curious about their function – removing them doesn't seem to affect anything visually beyond making the black background darker. Would you be willing to share your thought process behind including them?

My aim was to alter your setup as little as possible, just enough to make label work with decal. To be honest i would setup everything completely differently, but i didn't want to mess up your workflow and also i don't have much time to invest for this. As for the purpose of the mix map, it's there to enable separate controls for glass and label roughness. I named Corona color nodes accordingly, you can adjust them if you want to change the roughness of said elements.

I will try to to answer your other questions tomorrow or sometime later, it's late night here and i'm desperately lacking good sleep.

Hi Romullus,

Thanks so much for your help so far, I truly appreciate your assistance. Initially, I went with Corona decals because they seemed like the simplest way to achieve the results I wanted. However, as you pointed out, there's likely a more effective approach.

If you have some spare time and wouldn't mind, I'd be incredibly grateful for detailed instructions on how you would tackle this project.

As a Corona beginner, this project has been quite the time-consuming and frustrating experience. There seems to be a scarcity of tutorials specific to this type of work, and I find the Corona documentation lacking in detailed, relevant examples. This has left me scouring YouTube and forums for answers. While the Corona forum community has been fantastic and helpful, finding solutions to specific learning hurdles has been extremely time consuming. There's a definite need for more tutorials and resources geared towards those new to product visualization with Corona.

Again, if your willing, I would be extremely grateful for any help you can provide (even if its just pointing me to a relevant tutorial).

Thanks again for your time and support.

[Max] I need help! / Re: CTexMap not showing same RGB values as the loaded texmap

First of all, make absolutely sure you are using Gamma workflow, no OCIO modes, as these are not fully supported yet even with Corona 11 HF2 and Max 2025.

Then do as Romullus told - apparently the CTexmap in VFB is shown as "data image" and there is no gamma correction applied to it.
But when you save it out (even with default "Automatic" settings, no manual gamma override), the output is as the input image.
Just quickly tested this in a simple PNG file, everything seems working fine.

It seems a tiling issue to me.
I think you should enable the randomization for each tile, and then tweak the settings to your liking.

Hmm, it looks like there are some issues with this setup indeed. Corona to this day have troubles with handling complex refractive materials, so it's best to keep it simple to avoid potential issues. I made your glass and label with single material and decal should be working correctly now. You will probably need to fix your UV mapping, or masks, since there are some spillovers here and there, but i think you should be able to handle that on your own.

Hi Romullus,

Thank you for taking the time to look into this. Yeah, Corona definitely has it quirks, especially when using it outside of the archviv space. Unfortunately, I have not found a lot of resources for people using Corona for product renders, and since Corona was mainly developed for archviz work, I am finding it difficult to use for projects like this.

That being said, I truly appreciate your effort and the solution you provided. Your setup is very similar to mine, with the exception of the label and glass roughness additions in the glass base roughness slot. I'm curious about their function – removing them doesn't seem to affect anything visually beyond making the black background darker. Would you be willing to share your thought process behind including them?

On another note, with this method, it seems there's no way to adjust the size of the black background itself. Ideally, I'd like it to be slightly smaller on all sides than the surrounding non-displaced glass, creating a thin border of clear glass around the black label. Is there a way to achieve this effect?

Also, I would like to add a texture to the black background label to give it a more realistic look. However, I suspect I'd need to use a completely different material, like a black paper texture bitmap, to replace the flat black I'm using now. But if I plug a texture like that into the refraction slot of the glass material (replacing the current bitmap), I'm unsure if the paper texture would actually show through in the render.  Any suggestions on how to achieve a textured black label?

If it is purely for rendering and not for working in the DCC, the yearly render node is the best option as it is the cheapest one at $172 per year. So if you will need that rendering more than 3 months out of the year, it gives a much better pricing than paying for random months one at a time.

So if I had a lot of rendering to do I would need to buy say a monthly licence for my other machine which is roughly £57 per month? I have a year licence on my main computer. All seems like a lot of money per month for rendering…

« Last post by studiobasler on Yesterday at 18:05:23 »

Hello Forum,
short Question, can i archiv a pure red light without the inner Orange within Corona or do i have to colorize this afterwards in PS/AE for example.

Thank you for any advice.

Cheers
