A baking test scene

[Racleborg]

My workaround for the moment is on the first export to put very obviously different colours to the objects that are similar, grab the number after 1st bake, then re export with the correct material. A bit long winded , but it works.

I should have fixed the small black-border problem, before:

now:

Note: the problem was in the support for rendering baked objects in LuxCore, not in the baking process, so it was affecting only the rendering inside with LuxCore (not, for instance, with Eevee).

Note 2: it is very important to set the image map wrap mode of baked map to "clamp" (not the default "repeat"), otherwise you get the black border from other side of the map. The latest luxcoreui bake all command does that.

@B.Y.O.B., there may be some kind of regression related to Blender v2.81 (or the use of collections ?)

It was a conscious decision to make my life easier, but I can add the names back.

Just done this and and then needed to set the UV offset to U 1, V-1. That's correct to what has been said earlier I think?

For new users who don't know this , it might be a bit confusing. Could the V -1 be set under the hood and show V 0 in the node?

V -1 be set under the hood and show V 0 in the node?

Do you mean V 1 instead of V 0, zero seems not to make any sense.

[Racleborg]

...mmmm....thinking

I've attached an image (artwork )to hopefully show what I mean. Or maybe I've missed understood something?

Unmark uniform scale and use 1,-1 for U and V scale

Note: scale, not offset.

Unmark uniform scale and use 1,-1 for U and V scale

That explains why things haven't been working out this end.

Thank you.

I’m getting some good results with baking textures except with the Velvet shader +bump.
(Images attached)

With no bump, then all appears good. With any bump (just.5mm in this case), then the result is close to black in Luxcoreui preview (shown), and in the resulting texture.

Maybe the problem is connected to the points that Sharlybg raised regarding the Velvet shader's shadow terminations, but just in case it isn't ....
Thanks

Bump should be (and will be) baked in a separate map file. Does it happen without bump too ?
