Title. I assume it’s under wind conditions but I can’t find wind conditions

Scenario >> Terrain Properties...

Should pop up a dialog box with all the controls you need.

In that dialog there is a section for wind, where you can control the direction and strength.

Under that there is a section called "water" where there is area called "Normal Map" with a drop down where you can select the bump map of the water (which are your ripples).

Hope this helps.

Cheers

savetheday21 is correct!

A normal map is a bitmap image where each pixel represents the 3 dimensional direction the surface is pointing. Using the angle of the pixel to the light source a program can light/dark shade the pixels on screen to make it look like it is actually 3D. Even though it is only a 2D image.

NORMAL MAP TEXTURE EXAMPLE

So a large section of water could be drawn using only two triangles but look like it is 1000's of triangles. And it will interact with lights in the game in real time. Since the axis we are looking at is always looking back at us, normal maps are usually a blueish color.

There are other types of textures that give similar results these are referred to as Bump Maps or Height Maps.

Lady Xenarra: Does anyone else think that USF needs buffs? It feels like they’re on life support sometimes

Willy Pete: @Rosbone Ahh I missed that memo. I still think its a bad decision though. Adds frustration for players and isnt gonna make them that much money

Rosbone: It is also good they left it free until after the free to play weekend. Points for that.

Rosbone: But I agree, the cost to get a full decent Coh game pushing $115 US is not the best idea. Especially when it needs so much more work for casuals.

Rosbone: To be fair, it was a thank you to early fans right? They said it was not free for long and it would become a pay DLC at some point.

Willy Pete: Re-releasing free DLC so they can charge new players money for it. Brilliant marketing strategy
