Plastic material using VrayEdgesTex in a composite map as bump map

[Jussing]

Hi guys,

I'm trying to make a plastic material with multiple bump maps, and an VrayEdgesTex to create bevels. But I can't seem to do that with GPU.

I can use the edge map in a composite map if it goes in the diffuse, but not if it goes in the bump. Unless I switch to CPU.

Any ideas? (besides switching to CPU, as keeping everything as GPU is part of the test for me )

I had this problem before. Couldn't solve it . Would be great if there is a solution .

Do you need this?

If this equivalent to round edges? Cant be, right?

It is (rounded edges + procedural bump). You have edges tex as bump map. This is the way it works in V-Ray GPU since 3.5.

Awesome, thanks! That does the job.

my bad, I was seeing it as plugged into the IOR slot. lol sorry

any idea how I can combine vrayedges with some noise to make the bump material less even? Trying with vraycomptex but it doesnt seem to blend..neither does composite..

Just as I have showed?

I don't understand.
how would I use that to combine edgetex rounded corners with a noise map?

[savage309]

Probalby I don't get the question, but you can use the noise tex where I have used composite?

I'm trying to do this

He is using general edge Tex but I only want the rough irregular bump at the corners, not all edges.
Is that possible somehow?

[savage309]

As I have showed, it will blend the bump map that you add with the rounded edges. Not sure how to make the bump map affect only aroudn edges though.

[MANUEL_MOUSIOL]

That's what I'm after. I don't need perfect round edges, I want them rugged. I don't understand why edgetex round corners can't be combined..

It's a special texture that is evaluated differently from regular bump maps. It's on the "to do" list to make the radius parameter mappable, which should help to break the straight edges a bit. We also plan to add an additional bump slot inside the edges texture. I can do it in a couple of days for V-Ray Next, if you are in a hurry.
