Well you better believe it. I can cc you into the ticket if you would like proof. I hope this was a once off so I opened a new ticket, in the perhaps naiive hope that a different agent can offer more support...

For anyone interested, after contacting customer support at maxon, their solution was to scale up the scene 1000x and enable camera space render. This essentially just makes the black line smaller at the cost of having an incorrect scene scale. unfortunately this makes a desktop pc asset 2KM long and makes working with the scene difficult.. The black line is also still visible but much smaller, with SSS enabled it goes back to how it was before(not good). I have a project file here with the "fixed" version and the original version and for some reason, the water plane in the fixed version behaves differently in renders than the one in the original. they both have the same shader applied with identical geometry and are visibly the same scale (maybe im missing something regarding how scaling works in C4D) but one renders a black line and one doesn't. When I asked for more advice on why this is happening, CS agent said "can u not just use the fixed one". So, in the end, no clarity around why this is happening. I guess using camera space render is advisable when working with large scale scenes but this workaround of scaling the scene only pushes the issue under the rug and Id prefer to work in real world scale but i guess that's not possible. Also, somehow the project file is 100 MB, i have no idea how because I deleted everything that is not relevant to the issue and there are no image textures or HDRIs so Ive put the project file into a google drive here: https://drive.google.com/file/d/1phQZn6zwNl-nzraxBqhx8D9N0xsgA5L4/view?usp=sharing

It doesn't seem to be an SSS issue because with SSS turned off, it still happens. I cant for the life of me figure this out. The only thing i found was turning off cast shadows in an RS object tag for the opaque object seemed to have some effect on the intensity of the line but it still exists. Also this doesnt work on the huge ground plane but on a test cube only for some reason. I tried copying the redshift object tag to the ground plane and it made no difference on that particular object for some reason. I suppose i could scale up the scene to the point the line is barely visible but thats not really solving the problem. Will continue to troubleshoot I guess. before turning off cast shadows in RS object tag: after turning off cast shadows in RS object tag (This doesnt happen on the big ground plane for some reason): I opened a ticket with redshift tech support, I will update here when they respond

That doesn't fix it unfortunately.

I will do in future, thank you for the pointing that out mate. Although, I left in the image files because you said the original files was missing the image texture files.

Hi, sorry guys, here is the proper link! @imashination @MJV https://we.tl/t-A0fReXshBt

Hi all, I have a scene here with water and a deformed ground plane: Where the ground plane intersects with the water, there is an unwated black line at their intersection: I tried googling the issue and tried the following thing, but nothing worked: - Adjusted refraction and transmission sampling - Tweaking parameters in the water shader. - increasing subdivision on the water plane and also the ground plane - reducing dispersion on water shader - Adjusting IOR of water shader scene file is too big to upload here, so im putting it into a wetransfer: https://we.tl/t-JFBRfiaWJB Any help is much appreciated, thank you guys!

That fixed it, thank you mate!🙏

Hey @Cerbera any chance you had a look at the scene file? would appreciate any help you could offer 😅

My bad, I'm new here 😛. Im using R26 with redshift and here is the scene file. thank you mate. plugturtle-weird_shading.c4d

Hi all, I apply a redshift object tag to this simple mesh: I enable tessellation in the redshift object tag with the following settings: When I go to render I get this weird shading effect happening on hard edges: I have tried removing phong and materials, adjusting phong etc but nothing has worked except for disabling the tessellation. I just want subdivisions on the surface to allow me to displace it without any smoothing on the topology or the phong/normals. Please, any help is much appreciated! thank you guys.
