Bumpmap effect

Get help using Construct 2

Post » Sun Aug 26, 2012 9:34 am

So one of the under-discussed shader effects we have now is bumpmapping. It's a great effect, as shown in the Ghost Shooter demo, I just... have no idea how to utilize it.

If anyone's taken a look at the capx for the demo, can you explain exactly what Ashley did to the bumpmapped sprite? It's all blue and pink and whatnot. I just don't get how the whole thing works really, I just know the end result looks good!

I know it's a pretty huge subject when dealing with 3D, but do I really need to know all that to do what Ashley did in the demo?

Sorry for misunderstanding~
You mean how to apply normal map within C2?
Actually is very simple~
You made an diffuse map and bake a normal map for it~
I will use the Photoshop NVIDIA plugin~
Then put the normal map on top of the diffuse map within C2~
Select the normal map, choose normal bump in the effect~
It's on the most bottom, it's done~ =)AkiraWong2012-08-26 14:58:27

yeah, bumpmap in C2 is quite nice actually.
Just be sure your normal map have proper coordinates - you'll need to invert it to look properly in some cases.

Sweet, sweet, thanks! Now I need to figure out how to bake a normal map... I don't have anything fancy like Photoshop -- can I do it with Blender? I'll see what I can find about that.

Edit: Actually I think I'll go with Gimp. It has a clone of the NVIDIA plugin Akira mentioned earlier. Now for some serious trial and error!SullyTheStrange2012-08-27 06:58:10

@SullyTheStrange
Actually there have several ways to bake normal map~
You can use xNormal, CrazyBump or ShaderMap to bake it~
These software did a nice job on 2D and 3D maps baking~
xNormal is a totally free software, you can try that~ =)AkiraWong2012-08-27 10:36:57
