I think the first one looks quite nice, actually. Very nice work with the shaders, they seem to work exactly as they should.

Could you post a few from different angles, some that show the tail and the rear fuselage as well as the belly? Also I'd like to see how the normal map looks zoomed really close.


Anyone got any input regarding the size/depth of the rivets, panel lines, and other details? That's important for mentally calibrating what a "good" normal map should look like.

What normal map strength setting does the first image use in percentage? If that's, like, 50% strength then that could mean that one could make rivets for example 50% fainter, then use full 100% setting on your game, and that would give more "playing room" for deeper, larger details. Very valuable info, that.


I'm actually pretty happy about how the normal map turned out in general. I threw in an effect that makes the individual panels of the skin slightly "bulge" outward between the rivet lines and that really shows up quite nicely on the fuselage. I see a few mapping problems here and there, the lines don't join together exactly seamlessly, but I'd say those issues are not high priority to fix, especially in testing stage.

Dents and dings can also be added as desired, by the way. Technically, it should even be possible to use layered normal maps, which could be very useful for weathering or damage details, but I'm not sure if the memory constraints of operating with multiple 4096^2 maps would be realistic.

The bump map effect is controlled by a slider in the mod tool, so it's an artist controlled variable.

I am storing it as an optional parameter in the material settings.

I will package up the mod tool and upload it at the weekend so you can play with it yourself. It's really easy to use.

1) Lod the HIM
2) Fix any glaring problems in the material settings by clicking on the "light" button
3) Click on "Render" "Texture browser" and select the material you want to apply a bump map to.
4) Click on the "Bump" button

A new dialog will appear with full instructions on what to do next.

When you have added the bump map, close the texture editor.

On the main button bar you have a checkbox for turning the display of the bump map on and off, and a slider to vary the strength of the bump map.

At the moment I don't save any of the bump map settings, I don't want to break any mods for IL2.

However it is fine for testing and experimenting.

Well, we're really looking forward to this tool.
Thanks for your work.

Hi Ghost129er,

Here are some screen shots of your project with varying bump strengths.

But whenever they talked about him, they always had a slight smile on their faces.. And that, perhaps, maybe your answer.
