Importing without shaders

SteveM17

I have an item that loads with shaders, but I'd also like to import it without them. How can I do this? (Also I can't find the OBJ file in geometries, otherwise I'd import it from there.)

In Daz Studio items always have a shader applied to their surface, even if it's only the Daz Default shader. There is a preset for applying that, which you could use by selecting the item and all its surfaces (or hold down cmd(Mac)/ctrl(Win) while double-clicking the shader preset and tell it to apply to all surfaces, not just selected surfaces). I don't think there's a way to override material settings in the item, though a script could probably be written to load the selected item(s) and then reset all of their surfaces.

Ok, so this may not be a shader issue (I don't really know much about them). To be more specific, when I load up most props, in the surfaces tab there are sliders "horizontal tiles" and "Verticle tiles" and offset sliders for them. But when I add the prop I mentioned these options aren't there, but there are a lot of different ones such as "anisotropic" (whatever that is!). I want to be able to use the usual sliders with this item, if that's possible?

That sounds as if it may be a Shader Mixer shader, in which case you can edit it to add (or just expose) the Tiler Brick settings. Which prop is it?

In the Surfaces tab, select one of the surfaces and look at the top line...it should say which shader is being used.

The one with anisotropic sounds like it may be OmniUberSurface.  It has tiling, too...just need to scroll way down the list, it's near the bottom.

SteveM17

The top line says OmUbersurface, as you mentioned. Near the bottom are 2 sliders called Map Tiling U and V, but moving them doesn't seem to do anything, Is there anyway of using sliders "horizontal tiles" and "Verticle tiles" and offset sliders with this?

mjc1016

No, moving them doesn't show in the viewport...but yes it is tiling them!  You need to render to see the effect.

I usually type in whole numbers and use the spot render tool to check...

SteveM17

So it's a matter of trial and error? I've been messing around with the U and V sliders, but the jpg I tried using on the prop appears at a slight diagonal angle, is there any way to change that?

mjc1016

Select the item and do a UV view on it (it's in the View drop down, like selecting a Camera)...it may be that the UV mapping is angled...

SteveM17

I went to UV view but only got a blank white square in material mode, but with nodes it looks like this:

I'm assuming the part that it looks angled on is the large item in the bottom left?

Well, it's angled, so you will either need to use a non-directional texture, figure out an offset to counter act the angle, re-unwrap it or rotate the texture in an image editor.

That's one reason why some things won't retexture very well and need ones made specifically for the item in question.

SteveM17

Yes it's the bit in the bottom left. It looks like I'll have to use something else, but I'll still get use out of the original prop as it's really good.

Cheers for your info yet again.
