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.

[C4D] General Discussion / Re: Best Images for Dome Mapping
« on: 2024-02-16, 18:35:10 »
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):

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:

[C4D] General Discussion / Re: Corona 11 and Pyro
« 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.

« on: 2023-12-05, 18:18:26 »
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?

« on: 2023-10-23, 17:21:57 »
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.

Stefan beat me to it. A Corona Compositing tag on the geometry with SEEN BY GI unchecked will let the outside light in. It's unnatural, but can be done.

« on: 2023-08-17, 21:21:06 »
Here's how I do it -
Turn on Corona Mutipass from the Corona menu and add an ID pass. Click on the ID pass and change it's ID type to Material. Render to Picture viewer and when done rendering, in the Picture viewer window, switch to LAYER and check Single pass and save this out. In my example you can see different colors for each material - the cone and Cube.1 have the same material.

[C4D] General Discussion / Re: Very very slow development of new version of Corona, why?
« on: 2023-05-18, 01:38:27 »
I'll counter the OP and say Corona has always developed very nicely and consistently. I appreciate you guys releasing solid, stable releases and letting users work with upcoming beta versions as well. Everyone benefits. The product should ship when the product is ready, not to meet some arbitrary calendar date.

[C4D] General Discussion / Re: Motion Blur on backplate
« on: 2023-04-27, 23:16:10 »When blurring the backplate, remember to match the angle of the blur to the direction of the camera/car. Also, break your backplate into visual planes and apply a lesser amount of the same blur to each section with the far distance getting just a little blur. This is a very quick example using a still I found and very basic blur of the wheels.
If you want to go crazy, you can use a gradient to change the blur as the distance increases. Subtle, but adds to the realism.
Thanks Al - you should look at Virtual rig studio. I ended up buying it yesterday. Lets you draw multiple vector splines to direct the blur direction and strength. I'm still learning it, and this example is off, but here is my first (10 minute) attempt. Seems better then Photoshop for this kind of application.

« on: 2023-04-26, 20:15:17 »I am using https://www.virtualrig-studio.com/#index for motion blurring backplates, I am not sure if there's any alternative that is on par.
"Staging" Backplate = i.e creating fake camera mapped little world only works in super specific scenario, one that is particularly either super open (flat salt plane for example) or very clean strict geometry shapes (in front of architecture). Any more complex depth and the result would be terribly fake. Even dome-mapping looks rather terrible in most situations.
Oh this looks cool - thanks for the link. Downloading the trial right now. Path blur in Photoshop only took me so far. This is why I love message boards - so much to learn!
Also - some really great work on your site!
