How to prep texture of an object for iray?

If I made let's say a room in blender?
How to prep the textures for iray?
Because blender uses different engine.

Blender makes PBR textures that can be used in Daz, you just need the images and once in Daz you place them in the correct slot under surfaces and then save your project.

You will need to ask someone on the complete method as I only have basics and probably missed something.

Blender doews use projected and procedural materials, however, which won't work in Daz Studio - for practical purposes* you must UV map your model, and have textures that folow the UVs.

* It is possible to set up procedural shaders in Iray and 3Delight, but converting from Blender materials would probably be fairly fiddly.

So no procedural.

And everything needs to be mapped. Basically baked.

But will PBR textures downloaded from the internet always work in Iray?

Or.... PBR textures also could be designed  for certain engine only, thus may not always work in iray?

Richard Haseltine

PBR doesn't necessarily mean anything - it isn't a language or shader engine, so the label doesn't say anything about compatibility 9though maps should be fairly easy to apply to Iray Uber Base). Only MDL shaders are potentially usable in Iray.

Basically textures are just images, one can take whatever image, slap it on a (UV mapped) surface and apply the shader one wants, but then there are maps that can require some tweaking if they are not meant for the shader one intends to use.

Gordig

Any map will "work" in any render engine, so long as it's applied to the correct slot with appropriate settings. A black and white map can go into bump, specularity, roughness, AO, displacement, etc., but won't do much in a normal map slot, for example. Some render engines have the ability to use normal maps and BW maps fairly interchangeably, but Iray is not one of them, at least by default. It's just a matter of knowing what kind of data the map slot is looking for.

Oops made a mistake, it was Substance that Chris Cox uses to make his iray shaders in Daz.
