MRT with 5+ texture targets bound

[andyc]

Hi,

I really need to look at this some more tomorrow, but I don't seem to
be getting writes or getting inconsistent writes to MRT attatchment
points 5 and up. Is this a known issue with G3D? Can anyone confirm
having successfully used 5+ render targets with G3D? I'm using the
same code in a loop to setup all my attachment points so I don't think
I am just doing something silly here.

My hardware should handle it[1].

Thanks,
Andrew

I used 5 draw targets on the ISPM project and it worked fine on GeForce 280 and Quadro FX 5800.

I think the GBuffer class also uses 5 draw targets.

Hi,

thanks for your help. It turns out that I was doing something silly
after all. I can go up to my drivers/gpus max of 8 attachments with
G3D.

I saw you present this at HPG. That presentation is what actually
prompted me to give G3D a try.

BTW, I think it is both good and brave that you have the code up there
for anyone who wants to reproduce your results.

Best,
Andrew
