Acetone:


That's very easy to fix.

- Don't change F0, because is fixed for water.

- If you alter roughness, seams could become more evident.

-Change the fourth value of color; that's the opacity. I guess now is 0.1; try 0.3.

"color" : "0.6,0.6,.0.6,0.3",

Nice video! I guess you used the Chapala mesh, not the individual meshes... am I right?

Thank you :)
The water is more visible but a bit too greenish.


I did a test with the Chapala lake DIFF.dds file and realised why you didn't keep it for this version : the transition between the meshes is way more visible.


Do you know if there is a way to make the water looking a bit more blue? I tried to edit the Water_diff.dds in Photoshop but didn't find a way to fix this problem :(

It will look great!!!

Same solution:

"color" : "0.6,0.6,.0.6,0.3",

The three first values are for red, green, blue multiplier.

The transitions won't look the same. Is a diferent case:

- Chapala have only 3 layers.
- This one have more layers and rotated, to minimize seams.
- This rotation will cause different shading also. There are two triangles on each square and is the way the engine calculates shading.

If you are ok whit seams, try to leav the dummy instead (3 layers), and change the values on the dummy .mtl.

Thanks a lot !



I ended up increasing opacity a lot : seams are less visible that way and rivers in Alaska are muddy and not really clear :)
I still need to tweak colors a little, but I'm really happy with the result so far!

I ended up learning a lot about materials properties in Outerra thanks to you  ;D

Hi, Acetone!!!

I'm glad to help

My mistake with the diffuse texture. I forgot to made a final adjustment I made for Chapala. Give it a try also to this new .mtl

It is very important that you play with the sun time / day of year/ and your angle of view before you decide the settings are ok, because this will affect the appearance a lot.

Made a few efforts with KW71's mesh. It's a nice idea but sadly, it only looks good for specific viewing angles. So my question goes out to the devs: could you possibly do something similar with animated surface and more consistent lighting in the meantime, while we are waiting for the far away vector lakes and rivers?

Hi, 2eyed!

Check this new thread:

Is far from perfect, but is a little bit better.
