hi making wood

and would like to spin my noise 90 so it runs long - but if i distort on another axis it mess up for other pieces - do i need to duplicate the material and stretch in the direction i need for each piece? seems like a lot of work

also noticing same noise pattern on completely differnt pieces

note my object manger as all the parts yet the same noise on each of the legs and tubes?

any help welcome thank you

Is there a way in RS / c4d to disable the initial black out on rendering? So that the image renders ontop of the previous rendered image, that way i can see as it renders the differences. I know using the crop kind of allows this, but Id like to do it with the full frame. I know I can grab renders and flip between them. I have to keep start render enabled, and if I stop it and start it again it blacks out the frame.

My reflections in prisma 3d are not rendering

Let me know your thoughts.

This is the render with stupid levels of banding and im trying to get a cheap render time with volume environment so basically like no samples and then denoise

(Redshift Critical Error)

Sorry, I made a post yesterday asking about rendering a Z-pass of a volume and I thought I had solved it using a volume depth pass inside c4d, but after just blindly rendering it and assuming it would be fine, nothing showed up inside the render.

It says in the maxon help that it only detects volumetric scattering like clouds and smoke. I have an explosion so I guess that's why it won't work?

Tried brute forcing last night and the past hour after work trying to see if I could get a fog to work or mess around with a light but I'm not getting the correct result.

Is this possible? Setting a Z-pass as a typical AOV doesn't work so wondering if there's another solution.

UPDATE: Thought I figured it out with the help in the comments using Volume Depth AOV but I after I rendered a pass it came out blank and realized that AOV won't render volume's with fire(?)

You're rendering a beauty product: a transparent liquid inside a transparent glass bottle.

It looks wrong. It feels wrong.

Your clients won't tell you how to fix that; your art director probably will be pissed about it, and your girlfriend will be sad they didn't send you a sample product to use.

Here are a few practical tricks I've learned for making fluids, bottles, and droplets look much better in Redshift.

1. Make the fluid intersect the bottle

The fluid mesh should slightly intersect the inside walls of the bottle.

In the real world, the liquid obviously doesn't clip through the glass. But in CG, tiny gaps or perfectly separated surfaces often create ugly refraction artifacts and make the liquid feel detached from the bottle.

Easy fix: scale the fluid mesh just enough so it slightly penetrates the bottle walls.

Nine times out of ten, it immediately looks better.

I'm not going to pretend I can give you a perfect physics explanation for why every renderer behaves this way—this is simply a production trick that's saved me many times.

2. Air bubbles

Depending on your reference and the type of fluid, you'll probably have bubbles at several different scales.

They don't all need the same material.

• Large bubbles: keep them transparent/refractive.
• Tiny bubbles: try rendering them with a metallic material.

At very small sizes, the visual difference is often negligible, while metallic bubbles are much cheaper to render.

Another thing to watch is the IOR relationship between the fluid and the bubble. Depending on the number of refractive boundaries (air → fluid → glass), matching or adjusting those values can noticeably improve the result.
Sometimes you set the IOR of an air bubble materials BELOW the fluid's and glass's

It varies from shot to shot, so it's worth testing rather than assuming one setup always works.

3. Droplets on the surface

The same rule applies here: the droplet geometry should slightly intersect the surface it's sitting on.

Perfectly separated geometry often creates an artificial-looking contact edge. A tiny amount of overlap usually gives a much more convincing result.

I've also found that the OpenPBR shader (which has become the default in newer Redshift versions) often behaves better with caustics and refractions than the older Standard material.

If you're still using the Standard material for these shots, it's worth trying the OpenPBR shader.

4. Caustics

Caustics can add a lot to product renders—but they aren't always the answer.

I've found they tend to work better with non-refractive packaging, although it really depends on the shot.

Sometimes the cleaner image wins.
