UE4 for expose parameters in ubstance designer

hegvbwkeuyrv

so i made a procedural material in substance designer. Is it possible to control the things that i can control via substance' product in ue4 as material instances or some sort? I'm not really familiar with unreal engine so sorry if this seems like an idiotic questions.

I've done my research and my current hypothesis is no you can't

Obscura

Not in the material, but in the substance instance, yes.

What you are looking for is the term "exposed parameter".

@Obscura so each time i want to change the tiling for example on a material i need to reexport from designer?

@KurtR when he publish that, what did he publish the shader as? sbsar? so ue4 and unity can open sbsar?

I just noticed that you are the guy with the cable in the water. Last time I asked you to go to F youtube or google and use it before asking stuff, and then if we see that you also tried at least something, we will gladly help. But instead, you are just asking back again. Type substance in unreal into youtube and it will show you what happens. Or even better, import your substance and just see what turns out from it.

Get the unreal plugin either from algorithmic or the market place. Read through the documentation or search for some tubes to start to get a sense for how it works.

@obscura im sorry... this is the last time i promise i wont ask here with this frequency ever again. I did do research but my deadline is coming closer so i just ask whil im doing research so i have several opinion.

@KurtR, YEAH! i just got that plugin its awesome, but if i have the output as RGB compresseed material, i notice that i need to revbuilt the nodes right? and if i want to use vertex color to blend in between to substance material i still need to build the node by myself right? So my deduction is that substance plugin is really useful for specific material that has the parameters exposed prior before importing to unreal in substance designer right? if not importing as bitmap will be faster right?

Personally I use the bitmap workflow, so I personally would agree. For me it might be the power of habit that does it as well, but it just more comfortable with bitmaps. That might change.

oowh okay thanks!
