Hi,

downloaded my first glass material from substance source:

https://source.substance3d.com/allassets/b19557cdb7c6f77f569261627f8aa9bffd2914df?q=frosted%20glass

and imported with the substance plugin for ue4.26 installed.
on applying the material to my geo in ue there is no opacity to it. So i check the instance material and look for opacity/transparency parameter to tweak..however there is none..

So what gives?;) since when does glass not let light through!;)

Im aware that in Substance Painter you need to use a particular shader model if creating your shader from scratch but I would have thought the source glass materials would come ready...

If someone could point m,e to/or explain the process to get glass materials to be like glass via sbar import using the substance plugin for UE4 that would be great.

thanks
Dan

Hi,

firstly just to say I am also posting in allegorithmics surface Painter forum as this could well be an issue on their side.

But. using a OcclusionRougnessMetallic texture in the fashion as documented here [where the texture is non RGB [i.e linear] and Occlusion = R, Metallic = B and ROughness = G]:
https://support.allegorithmic.com/do...nreal+Engine+4

I get the following visual artifacts on my shader as per attached.

IS there something I have missed? from The shader preview and viewport views it seems that this texture [the linear one] is somehow creating these visible artefacts
but I have no idea why..

Any help would be much appreciated.

Best
Dan

hi,

really new to substance and exporting uv'd models for substance [and then hopefully unreal] but what am I missing here.

I UV my asset, giving different material IDs for the materials that come in ok, and then I bake maps but on adding one fill layer and then a standard on top i find it nearly impossible to paint the asset[on the standard layer with a brush] and when it does it creates the effect as in the attached image as if it is painting on each uv square...

to note: only seems to paint when the brush size is large and when i hit a sweet spot on the mesh..

can anyone help with what i am missing/overlooking?

thanks
dan
