Hi everyone,
I’m using D5 Render Pro version 2.9.1 with an RTX 4060 GPU. I mostly render 4K architectural visualizations (camera height about 160 cm) — exterior scenes with a house and grass in the foreground and middle ground.
I’m having trouble with grass rendering quality — even at the highest settings, the grass looks grainy and noisy, with a kind of “moire” or aliasing effect. It doesn’t look sharp or realistic like in professional renders I see online.
Here is what I’ve already tried (no improvement so far):
Using Scatter tool with ready-made grass models from D5’s own library
Switched to different HDRI lighting — same issue
Reduced scatter surface area — no change
Tried different types of grass (including “recommended by D5”) — same issue
Set rendering to highest quality settings
Enabled and tuned DOF (Depth of Field) — still grainy
Camera at 160 cm height (so not an extreme close-up)
Updated GPU drivers to the latest version** — still the same issue
I’m currently rendering at:
4K resolution
RTX 4060 handles it fine — no crashes
My scene looks well lit and detailed — except for this grainy, unsharp grass.
Is there any setting or trick I’m missing to make the grass look more realistic and clean — like in the showcase renders?
Could this be caused by the built-in grass models (Scatter) in D5? Should I try external grass models?
Any recommended scatter settings or post-processing tips for sharper grass in 4K renders?
Any advice would be super appreciated — I’ve tried everything I could think of!
