Want Decals ? ^^

Stormtrooper showed me a list of missing features, one thing that bothers me too, quite while was the missing support for decals ..

So i made up a few textures :)
Those a still very simple, not to mentioned that the decal feature so far is not implemented yet.

But i think i show some example, to give an idea how this will look like:

Notice the two penetration types, one is "stone" the other one is "metal" there will also be wood.
All decals can have a normalmap or more if needed.

Well, good job on the decals, but... The stone decal looks like its for a soft stone like sand-lime brick... For a harder stone, something like this would be better

Here an example for wood...

Soil...

And... @Carsten & Kai: At the same time those impactare being created, you should also add those things that come out/split out of things when you shoot it. (I already talked to you, Carsten, about that in combination with the materials system ;) )

Examples:

Metal

Stone

Soil

Have fun ;) Pics have been taken from Call of Duty: United Offensive

*g* i knew you would like it :)

Of course it is very important that a bullet impact or penetration also produces sprays of materials or fragments. This is a job for the particle system, and i dont know anything about the capabilitys of the one, Carsten implemented.
Later it would be very nice to bind it at the physicsystem

Trails for sparks and such things can be added quite fast .. a real complex particle system can be very big ..

Oh and for the stone decals:
Well my example is just a photoshop based version, if i look now its not very accurate in proportions.
However i must disagree.. your first example looks not really like an impact into hard stone..more like someone sprayed ink on the wall :roll:

See, i fired bullets myself on stone and wood when i was at the army. Most common used ammunition will not just create a hole in the rock .. (your example looks very soft by the way ;)
Stone is pretty hard but also fragile, so in most cases the upper surface will broke apart and produce some debris.

Well thats just my personal exp. and so far decals are not yet working. If there is a working version you can tell me, what looks right and what should be changed :wink:

Hello!
Kai, I really like the decals that you've created!! Best bulletholes I've seen ever. :) Make sure you send them to me for inclusion with the next release, I think it should be easy to integrate them right now. (However it's right now not so easy to distinguish among wood, metal, ... etc. This will take until the MatSys is complete. As has already been suggested, we will need an additional material property for this purpose.)

i agree those are very nice bullet holes. r they normal mapped aswell? the particle flakes coming out should not be that hard to implement. just difficult to get the right 'feel' to them. stormtrooper some of your holes look a bit odd. as a regular shooter i do not think they look very realistic as the material will flake as the material underneath it expands and pushes out. i would be happy to provide some real reference photos of actual surfaces after i go shooting again.

Thx :wink:
r they normal mapped aswell?
Not on this image but if you want you can also activate a fitting nmap.
By the way, i always appreciate reference images/photos

They are okay but not outstanding, have seen better ones. :)

I don't mean to be harsh or anything, but for those of us that have been stupid enough to shoot a rock at close range, they tend to chip or just lighten in color, if it is hard rock, even if it is shot with a high-caliber gun. I've never seen a gun leave blackened holes in a rock. But I found the soil to be satisfactory although the grass looked sorta low-res and the decals high-res. The metal was the most realistic, but the sparks would only be that visible if it was dark, or overcast, not a sunny day like it appears to be. If the sky is bright, then as few sparks would be visible and a dent would show in the metal, as well as some discoloration. I'll post some reference photos as well Shadow! But otherwise, these decals are great! I enjoy looking at others work and use the things I liked about them. I shall use the sparks, but not overdo it, I like the splinters from the wood, but I'll make the decals more realistic, I'll make soil decals match the resolution of the grass. Other wise I am very pleased. Unfourtunatly, my web browser did not load the image of Kai's decals so I cannot offer any insight to it. :(
