Hey guys so im having lots of issues with the global illumination render.
Basically it looks like Terragen doesnt take into consideration the bounces of light on the surfaces.
I have rendered this image where the sun is high in the sky, i have these palms model with just a plain diffuse texture both on trunk and foliage.
The problem is that the face not lit by the sun are super dark. Now in a normal environment this shouldnt happen, because the Light from the sun bounces around and hits the surface from the back, bouncing off the ground.
In every 3d software the global illumination does a good job and produce a more or less accurate result, in Terragen im having this issue where everything is really black as if there is no secondary bounces of light.
My settings are also high but i noticed no difference.
here they are:
Path tracer: 25 Landscape
GI settings: Gi cache detail 12 | Gi sample quality 12 | Gi blur radius 8 | Supersample prepass on.
anyone have any clue how to increase the overall global illumination bounce?
if you take a look at the docs, here
https://planetside.co.uk/wiki/index.php?title=Terragen_4_Global_Illuminationthese 3 renders, it looks like my render is just lit by Direct illumination. while if you check the "direct + indirect" the foliage and the overall shadow blackyness is way softer, look at the ground the shadows arent that hard black. Something is wrong
in the zoomed image you can see the shadow projected into the ground from the tree trunk its way too dark. It shouldnt be like that considering how strong is the sunlight
