Make VRayEdgesTex work with "Isoline Display" option of TurboSmooth

[Art48]

When rendering wires for various purposes I don't want to take the fully tesselated mesh edges but rather the original, unsmoothed edges but with the smoothed geometry so I turn on "isoline display" in the TS modifier but vray acts strange and produces jaggy/splotchy edges....can we have a fix please?

A temporary fix is to collapse the turbo smooth modifier in to editable poly. The isoline display then becomes the actual topology after that, which I painstakingly found out once.

Ah thanks! Good to know!

Although I don't think that fixes the rendering artifacts of VRayEdgesTex. The invisible edges still cut into the lines of the visible edges.

What you can do is add an EditMesh or EditPoly modifier, activate the edges subobject mode and select all edges via Ctrl+A. Then click on "Create Shape from Edges" or "Create Shape" (depending on Mesh or Poly) to create a spline object of just the visible edges. Now you could already set that spline to being renderable and use it as a wireframe, but of course that way the lines will have their thickness visible along the silhouette of the object. Going further you could set the (renderable or sweeped) spline to being non-renderable (in the object properties - not the EditableSpline's settings), and feed it into a VRayDistanceTexture, so that it will create lines on the object's surface.

Wow, that DistanceTex workaround is genious! Thanks for that! Best would still be to have it supported natively though

Wow that's some imaginative use of the distance texture. I'm always amazed what users come up with

You can even use the DistanceTexture in the bump slot, if you need precise imprints, via splines drawn on the surface of the object. No need for unwrapping and more detail than a bitmap.

Can it be used directly in a VRayDisplacementMod? ^^

Yes...

distance texture has been my favourite map for quite some time.. its -extremely- useful.

Beware that collapsing your turbosmooth +Isoline Display in a poly will mess up your surfaces (there are no such things as invisible edge in poly) Editable mesh is the way to go.
