UV Tool

[gordonrobb]

I'm sure I'm missing something. In the lightwave plugin, if I want to apply a texture to an object that has no UV set up, I can connect a UVTool (can't remember what it's called) to the normal, and select various types of projection.

Is there a similar node in Standalone? Cannot for the life of me find it. If not, How can I project a texture onto an object without it having a UV?

Want to do some testing between versions.

Anyone?

I think that in standalone you always need an UV map to apply a texture image, there isn't an implicit texture projection node like the LW one, AFIK.

you need to unwrap all your objects in your 3D software before bringing it into Octane

Well that's a bugger - or great for us LW'ers, depending on how you look at it.

@Gordon: I mostly use the standalone and I've never had to use a no-UV node on any of the nodes in order to add a texture: I just apply the texture and it goes.

Caveat: it's possible that zbrush, maya or marvellous designer (my three tools of choice) all auto-generate some kind of default UV when exporting the OBJ.

I haven't, however, explicitly created UVs in all cases and have just exported the OBJs with the intention of applying either a seamless texture or a procedural material in the standalone and it has just worked.

procedural textures use world space, not UV space, so you can use these without having your model unwraped. Also, they are not effected my your models UVs.

That's ok. I just wanted to try something in Standalone that I'm doing in the plugin, but it's using a texture image on an object with no UV (that's about 800K polys).

I wont bother, or maybe try it on a simpler object.

@Gordon:

If your texture is seamless it might still work. You don't lose anything by trying.

[gordonrobb]

I had tried. That is why I was asking. It's ok, I' can create a UV on another mesh and try it. Got distracted by other stuff at the moment
