Title: Pin Material
Post by: monsieurblack on 2022-02-15, 18:59:15

Hi all

Just after a little help with the "Pin Material" tag in Cinema 4D please.

It seems to behave properly when applied, so viewport is showing the correct behaviour and in turn renders properly in Standard/Physical.

Unfortunately my problem appears to be that Corona doesn't appear to honour this :/

So like I say, the viewport looks fine but as soon as I hit render with Corona it's seemingly ignored.

Feels like a 'bug' but not 100% sure so posted it here just in case. (mods feel free to move it to the other forum if it proves to be a bug)

Definitely frustrating, so any help and/or word of how others get on with this would be super appreciated please.

Thanks in advance

Checked it, it works when rendered "normally" but is ignored in the IR.
Definitely a bug.

For those who don't know (such as me), what is Pin Material meant to do?

It fixes a material in place to stop it moving

See the attached scene.
Compare the Viewport view, the IR result and a rendered result. Only two look alike.

PS
The Pin Material tag pins a projection other than UV to a mesh and when this mesh deforms, keeps it in place. Here it keeps a planar texture projection stuck. Or not.

Thank you all

Re-assuring to know I'm not going mad :)

@CineMike - I appreciate you checking and can't believe I didn't try a 'proper' render. I just assumed they use the same 'render' so what I saw in my interactive window would be the same.

At least it didn't stop me doing what I needed, phew!

Thanks again everyone 👍

Is the Pin Material the same as Stick Material? I assume they changed the name of this feature.

That's right.
