Questions about LWRP

Postby DuvE » Mon Sep 17, 2018 2:14 am

Hi. I have some issues when starting to convert some of my shaders to the LWRP template:

- Is it possible to achieve AlphaBlending with LWRP template? I know you can't use GrabScreen but maybe there is some workaround?

- When I'm trying to use node "Gamma To Linear" on one of my LWRP shaders, I get this error undeclared identifier 'FastRBGToLinear'. The error appears only when I use this node and plug the outcome result to the "Vertex Offset" of the LWRP Template. If, for example, I plug the result from this node to the Albedo, everything works fine without any errors, but I need to use this node in "Vertex Offset". The shader in the attachments.

Hello, I've just confirmed the error on my side and have passed it along to the developer for further investigation, thank you for taking the time to report it!

Regarding your first question, you can achieve transparency on LWRP by accessing the Output Node's parameters, going to your Subshader Tags over the Subshader section and replacing the Value text field contents on both RenderType and Queue items with Transparent.

After that, simply go to your Blend Mode over the Pass section and on the Blend RGB dropdown select Alpha Blend.

With these settings configured, the transparency amount will be given by the value you specify over the Alpha port on the Base Output node.

Please let me know if you have any further questions, we'll be sure to get back in touch as soon as we've tackled the reported issue!

Hi,

One more issue, now with HD unlit template. If I plug "Switch by Face" in any output, I'm getting this error:
undeclared identifier 'ase_vface'

Weird, but in HD PBR this node works fine.
