thats a pity... i can convert c4d layer shaders to vray layer shaders but cant do it in the other direction, because i cant create layer shaders ... sigh

yup.. well.. i dont expect that to change very soon... so i guess we have to live with it still thanks for your patient support

damn. totally didn't look there. sorry. Alfie

Hi, thanks but i managed to fix it. It wasnt a Cinema4d related error. Apparently a bad argument to one of python methods was causing it to return the filepath of the script instead.

For viewport delay: i rewrote Skin Deformer ,Add a Aim Object to Check DeformCacheDirty To achieve my purpose（keep viweport realtime Refresh），yes ,it work. I have been updating the post, hoping that I can understand what the problem is on the right path, instead of exploring the working mechanism of Cinema 4D in other ways. Although I don't get the official answer, this will not dispel my enthusiasm for exploration the answer. (English is not very good, I hope to understand what I express)

Thanks for the solution and explanation Yannick. It's working perfectly now and I can finish converting my scripts.

Thanks dskeith, that code worked perfectly. Thanks for that!

Cool. Will do.

@mikeudin Thanks for making us aware. We'll change the link with the next docs update.
