If I add a graphic to an object, is there a way to set a blend mode so that the texture of the object shows through? Similar to Photoshop?
The only thing that you can do with graphic is to customize its opacity or (opacity map). IMHO the another possibility is to use color light or Substance Material that include some custom material properties. See capture. Also you can render PSD file and add blend there.
What @Ares Hovhannesyan said!
You could also"capture" the material from the object using ha! Adobe capture 😉, and create a material from there. You could then import it to Dimension and not content yourself with ready-made materials (or have to acquire Substance sampler).
Unfortunately, as far as I know you cannot use the capture module in Photoshop to create material, you can only use the mobile app (but it's included with your CC sub)
However, there is now a material panel in Photoshop where you can apply materials (as a pattern) onto your artwork. You jut can't create a material from scratch...
translucent vs opacity... there is no blend
it was an option in early builds of Dimension and there are still some base materials on Adobe stock that you can make into what you need but true "translucent" was dropped when Adobe moved to metal drivers instead of Nvidia standard
note thats across the entire Adobe range from Fuse, Dimension, Photoshop etc that shows 3D... there are workarounds depending on what % you want to show but if you are following an older Adobe tutorial [and don't have that build] then you are out of luck now
