I might be able to help. I have been dabbling with the BRG for a while now.

#

oh cool. Alright first off, all i'm gonna be honest that i'm totally blind on BRG,
which is why i'm trying to understand how it work or how to use it.

#

And someone from unity in the forum point me out to the script above, but obviously i'm getting error.
it told me that i have to use HDRP or URP to use BRG, but thing is i already did on HDRP

#

Now i'm totally wondering is there a working template or repo for BRG? I was wondering especially after Sebastien Tweet where he convert the Viking Scene into BRG

#

Thanks for offering btw

#

That test project is the code from Sebastian

#

You say you are getting an error

#

What error?

novel egret Apr 19, 2023, 6:32 PM

#

RenderBRG.cs(751,12): error CS1029: #error: '"You need either HDRP or URP package to use this script

rapid isle Apr 19, 2023, 6:32 PM

#

Then your project is not set up to use either hdrp or urp

novel egret Apr 19, 2023, 6:33 PM

#

like i said above, i already on HDRP

rapid isle Apr 19, 2023, 6:33 PM

#

Do you have a render pipeline asset assigned in the graphics settings ?

novel egret Apr 19, 2023, 6:33 PM

#

yes

rapid isle Apr 19, 2023, 6:34 PM

#

Hmm ok the defines are for hdrp/urp 7.0.0 or newer what version are you on?

novel egret Apr 19, 2023, 6:41 PM

#

16.01

rapid isle Apr 19, 2023, 7:03 PM

#

Well this is strange…

novel egret Apr 19, 2023, 7:04 PM

#

hence my confusion 😓

rapid isle Apr 19, 2023, 7:04 PM

#

Try deleting those defines just to test what will happen.

#

But this is really strange the defines worked fine for me

#

On unity 2022.2 not sure what hdrp version im using

#

I have to sleep now but I will check in tomorrow

novel egret Apr 19, 2023, 7:09 PM

#

Alright Thanks a lot

#

without defines it compiled btw

rapid isle Apr 19, 2023, 7:11 PM

#

Hmmm

#

Can you try a fresh project on hdrp 16 and just put the defines in a script file

#

Like #if newer else error

#

If it errors there I think you have a bug report on your hands blushie

novel egret Apr 19, 2023, 7:17 PM

#

Oh btw, it work but there's a message
Converting 0 renderers...
UnityEngine.Debug:Log (object)
RenderBRG:Start () (at Assets/Scripts/RenderBRG.cs:792)

#

without defines just fyi

#

anything else do i need to do to make renderers using BRG?

#

oh i see, it looks for child renderers

rapid isle Apr 20, 2023, 5:46 AM

#

Hey, Im back did you manage to get it working?

novel egret Apr 20, 2023, 10:50 AM

#

i think i got it to work, but the transform are all messed up

#

i'll send you a screenshot later, currently afk atm

novel egret Apr 20, 2023, 11:43 AM

#

So this is before play mode

#

and after play mode

#

#

somehow all mesh are scaled and rotated to a single point

#

also it seems material are incorrect too

#

so i guess in term of is it work. . . well kinda 😅

rapid isle Apr 20, 2023, 2:14 PM

#

Interesting I had almost the exact same bug when I started my own imlplementation. This suggest that either the matrices are uploaded wrong, the metadata points to the wrong spot in the big gpu buffer or the draw commands indices are wack

#

How ever both the test script and the code from the gpudriven branch worked for me once I got them to compile

#

Do you get any errors at all ?

novel egret Apr 20, 2023, 3:08 PM

#

nope no error

rapid isle Apr 20, 2023, 3:43 PM

#

Well I will have to test out the whole branch on my end. Too much can be wrong to debug like this.

novel egret Apr 20, 2023, 3:46 PM

#

appreciate it , no need to sweat it though, i know that it is experimental.

rapid isle Apr 20, 2023, 4:25 PM

#

The thing is I specifically remember that code working for me mostly out of the box once I got all the scripts in.

novel egret Apr 20, 2023, 4:38 PM

#

ooh i see
