hi guys, :smile: im having a bad memory error whit displacement maps, im doing a scene where i used lot of displacement, then i made it bump and renders ok , but when i add even 1 texture whit displacement it creates error not enough memory the disp size is 4k resolution if i use less size it renders but i dont wanna loss quality, i have tried everything bitmap pager, dynamic memory 200mb,400mb,800mb and 1800mb ,in less words i wanna render a big displacement map but my memory cant handle it is there any way to do this? or im doing something wrong in the system settings , thanks for any answer

Ive had issues with this, although not with displacement maps (just 16k wide diffuse maps :lol: )

Try splitting the surface into equal sections and using the corresponding area of the displacement map over each one. Another advantage of this is that if its a still and the surface goes pretty far into the distance, you can lower the resolution of the maps used further away.

Are you using 2d or 3d displacement? 3d is often faster and less memory consumptive.

thx for the answers im using a 2d disp tried it on 3d but loss lot of detail i think that will be my only option.

is there any way to render this in layers and composite? whitout lossing reflections and bounces?
