Came across this after rendering an image for a client. I like to slightly motion blur my people in situations, set off a render in queue last night with the introduction of some volumetric fog to my scene.

If the Volumetric object material is on a mesh which covers your selection, it doesn't render the selection.

Maybe it's just this way but thought i'd bring it up. I can set up a small scene if you aren't able to replicate it later on to show what i mean

I'm having some issues sometimes with Material viewport preview size since updating.

When you switch from a lower size to a higher dimension it can freeze for 10-15 seconds or more and lags for a couple minutes before the viewport is useable again. It happens on Procedural and bitmapped materials.

Here's a boring video to watch of what i mean :P. I'll leave it to you to discuss. I can use 512x512 for now with about a second lag

Hey, in the new candidate release, when saving from the VFB the save button / Save all button, defaults to openexr as expected, but it seems to save out .rla files.

There is a work around if you flick between one of the other file types and back to openexr file time, then it saves exrs but as said above it seems to default to rla.

Could one of you take a look at it when you have time.

This is on MacOS, c4d r21.026, Corona Version 6

Cheers,

Any other information you need, let me know.

I've been playing round alot with lightmix lately, but as it doesn't have denoise function. What is the correct way to comp lightselect layers so that it is the same as light mix if anyone has a workflow for this that would be greatly appreciated

[C4D] General Discussion / Light Direction - Viewport Icon
« on: 2020-07-21, 13:43:30 »
Just wondering how you can tell the light direction from the viewport icon? In max you have it so the Light direction is shown as little rays coming from the rectangle. In Cinema it is just a star in the centre of the rectangle. Bit confusing to me to have it shown like this. Maybe there's a way of showing it as a direction

Can vray scenes be converted to corona, like in 3dsmax or was that support not implemented?

Has anyone found a way to save corona layered materials in the content browser, without losing it's connections.

Say for example i have a Leaf material, with a Front and back side in a layered material. Once save to content browser and brought back in to C4d R21, it still brings in the materials but not in the layered Material.

https://www.rendertaxi.de/blog/en/how-to-create-and-set-up-corona-proxies-in-cinema-4d/

Just reading this article on proxies. I always had trouble getting them to work, but i see you need to put the texture tags from the original model on to the proxy for it to show materials! A little different to 3ds Max.

However, they mention in the last paragraph that :

"Nevertheless there’s still a big drawback when using corona proxies in cinema 4d being that the visor of Cinema 4D becomes very slow while working with proxies using any display modes of the proxies. We actually don’t know if it’s a Corona performance issue or a problem native of Cinema 4D which is not yet able to handle the proxies. We hope that Corona or Maxon developers work together to solve this inconvenience soon!"


I remember when i used 3ds Max, the huge benefit proxies had on Chunky scenes. I was just wondering if the dev's got to the bottom of this?

[C4D] I need help! / Brick Material Shader
« on: 2019-09-22, 14:01:32 »
Hi there,

I'm looking for some advice, tips on a way to produce a shader that replicates the following Reference. It is a brick that has one chiseled face. It's for a personal animation project i am looking to do, which will involve one shot of the sunlight rotating round the eliptical facade to show off this chiseled detail.

Therefore i need the bricks to be each unique.

i was hoping to use a selection tag to displace one face and use the variation effect to create variation in the UVW noise so that each displaced face is unique. However, it produced an undesirable result pulling the displaced face away from the rest of the brick, which makes sense.

Second try was splitting the displaced face away from the rest of the model and closing the hole. I think moved this face inside the brick so that the displacement would look as if it came from the brick. However it just seems a little messy, i feel like there could be a better way to create this.

Thanks in advance. I've attached a basic scene, with what i have so far. Feel free to play with it.

[Max] General Discussion / Vray Swarm
« on: 2017-01-25, 14:27:40 »
Up and coming for chaosgroup, looks like they are creating a swarm DR system. Here's the link :

https://labs.chaosgroup.com/index.php/rendering-rd/understanding-v-ray-swarm/

Is there anything in the pipeline for this to be implemented in Corona. Would be great to get some weaker machines we have involved in the rendering, currently they love to bomb when they run out of ram :P.
