Thanks Corona! You've been a huge part of my career for the last 10 years and help keep a roof over our heads and children fed. We really appreciate everything that you do. Still my favorite render engine of them all!

I have faked this in the past by modeling a simple Flame shape from a flat plane/polygon and used a luminous texture. Lots of easy ways to lightly animate this if you need a flicker or movement.

Here is a sample scene that shows a basic version of the setup. Thanks in advance for any ideas.

[C4D] I need help! / Control Emissive Material texture via Xpresso/User Data
« on: 2024-05-15, 22:03:27 »
Hello!
I am working on an Xpresso rig where I need to end user to drop a texture into my user data slot and this would become the texture for an emissive texture on a plane in the scene. I have the setup working correctly in Redshift, so I know My methodology is working overall. It's all simple set driver/driven stuff.
With Corona, when I drag the material into the Xpresso window, there is no port for Emission Texture, only Color (& Color R,G,B) - am I missing something? Connecting to the color port isn't working and when I try to manually drag the texture field from attributes to the node, it lets me make a Texture port, but it won't let me connect anything to it. Weirdly, I can choose Texture from the OUTPUT side of the node but that does nothing to help me.
Any thoughts here? I realize this is an obscure request.
Thanks,
e.

Really excited to try Vantage out. I'm learning Unreal, which is great, but Vantage might hit that sweet spot in between that is just what I want.

Not sure this helps, but I've used this one with Dome very successfully.

In general, the higher quality ones I've used tend to be better, I know that's not solid advice.

[C4D] General Discussion / Re: Volume Material - How to add the steam to god rays in a bathroom scene
« on: 2024-01-24, 16:29:02 »
I would approach the steam using a VDB file. There are many out there and you can buy packs like this (some animated, some stills):
https://www.thepixellab.net/vdb-smoke-pack-volume-1
You'd have to play with the settings a bit to make it more steam like and less smoky, but that can be achieved. Take a look at this:

« on: 2023-12-05, 19:48:33 »We have Pyro covered in our Help Center and Documentation:
https://support.chaos.com/hc/en-us/articles/4528489581329
https://docs.chaos.com/display/CRC4D/Corona+Volume+Grid
If it's not clear enough, please let us know and we will do our best to improve it.
Also, feel free to register for our live webinar https://corona-renderer.com/webinar-chaos-corona-11 (plus we will most likely release some Pyro tutorials in the near future).
Thanks Maru - I would say those steps are rather buried in the language and could be more prominent. Thanks!

« on: 2023-12-05, 19:45:46 »
A few ideas:
Render them without glaze - render them with full glaze (maybe puddles as separate SDS objects) and then do some creative masking in Photoshop - will still require some highlight painting.
Great the glaze material and place it as a second material over each ball and then create a custom opacity mask. Again - puddles as sperate objects.
You won't get it perfect, but I bet you get it close enough that hte post touch up isn't too bad.
Could a glaze DECAL be useful here?

Oh never mind - I am dumb and just for Ben's thread in the other forum.
Short answer for anyone reading. Add an object and add the pyro tag. Add a Corona Volume Grid and add the Pyro Output to the OBEJECT PROPERTIES box. Weirdly, drag and drop doesn't work here, but the eye dropper tool does. Ignore the Error message and off you go.

I see in the marketing release that this version works natively with Pyro, yet I can't get it to work. Any guide or help files to show how to set this up?
My "high tech" experiment was adding a sphere, adding a pyro tag to it, running the sim in time. Render. Nada. What am I missing?

I can't speak for the OP, but for me - not all rendering is realistic or Natural. Most of my renders are inside arenas or stadiums and there are times when I need to render out simple shots for geometry discussion or pipeline workflow verification that aren't about being lit, but just need to be seen, and while I can set up a lighting system for this, it's usually quicker to just toss a big HDRI in there and have it blow through the geometry of the arena.
