Multipass render workflow. Excruciatingly slow.

[MancDan]

Recently we decided to try out Affinity Photo on PC, for the sole reason that we can work in full 32bit mode with our CGI rendered .exr's, with full access to 32bit adjustment layers and layer modes, something that Photoshop limits unless you go down to 16bit!

We work with large .exr's, were talking up to 5-6k pixels.

We generally have our main RBG beauty pass as one layer, and then sometimes up to 7-8 other render passes (reflection, GI, shadows etc) at the same resolution and bit depth in the same document. This is where Affinity starts to really, really struggle. Clicking on a layer, adding a new adjustment layer, adjusting an adjustment layer, Affinity just grinds to a halt and freezes over. In PS, things slow down as the file becomes larger, but no where near to the extent I've experienced in Affinity.

Is there anything we can be doing to improve performance with large files/documents?

Hi MancDan,

Welcome to the forums

If possible could you provide one of the files in question and the steps you are taking in PhotoShop and Affinity so I can investigate this further for you?

This is difficult due NDA.

 

I will throw together a simple scene.

 

Thanks
