Adding new texture and eye flashing to droid model "C_ForDrd"

[Sith Holocron 2,514]

Any chance I could get a new texture for this droid model?


(The model name is "C_ForDrd".)

Bonus points for using Darth Sapiens' cubemaps research . . .

I wonder if you could use elements from the textures for C_ConDrdBoss, C_ConDrdL, and C_ConDrdM as a basis? They are all basically the same series with obvious shared similarities, yet those three have 1024x1024 diffuse textures and normal maps, yet C_ForDrd just has a 512x512 diffuse. It may require a remap to accommodate that though, which is likely more trouble than it is worth.

Thanks for the tip, DP!

Who's on the case? I have a decent progress on the rodians, so I might have some chance to work on the droid.

[Sith Holocron 2,514]

Who's on the case?

Hopefully you . . . and anyone else I can rope into this!

Here are some screens of a 1K upscale effort:

I had been planning to work on a new vanilla-upscale pack for all the droid textures, starting with the protocol droids (because I throw up in my mouth a little bit every time I have to talk to one), but since this request came in I figured I'd start there.

 

It also gave me an excuse to develop/use a new (to me) technique, which is using 3d modeling software to bake an ambient occlusion map (in my case the software is blender), and using that map as a shading layer for the diffuse texture (since KotOR doesn't actually have direct AO map support). It works incredibly well on droid textures. On skinned models, it is less helpful, but can still add a little bit of realism (if you use a high opacity on it it makes the model look dirty/wrong, but a little bit goes a long way). At least in Blender, with KotOR models, there's a bit of art even to getting the maps baked properly, so I hope to write a tutorial out before too long ...

 

Anyway, hopefully people like it, let me know! I'll start a WIP thread if I start to make real progress on other droids.

If MDLOps could ever be fixed (or at least made less broken), we could import some new protocol droid models.

Are you using xNormal for your bakes? I usually find that the easiest route, assuming you are creating a high poly source mesh via a subdivision surface or the like.

[Malkior 477]

I have my own texture that looks good with an exception of the eyes.

 

 

 

 

Is there maybe a tutorial or simple method to fix this? 

[Sith Holocron 2,514]

Might anyone be able to assist Malkior with how he can get the droid's eyes to glow?

[DarthParametric 3,808]

Self-illumination, if that is what you are talking about, is handled in the mesh, not the texture. The original model doesn't have any self-illum for the eyes because they are part of the head mesh (and obviously you don't want the whole head glowing). There's currently no practical way to address that for this model. It's not something that can be hex edited, because you'd need entirely new meshes for the eyes. Trying to compile a new model will almost certainly not work due to the issues with MDLOps. The only option is to fake it in the texture, the same as the original texture did. Start by cranking up the brightness.

[Malkior 477]

Unfortunate..

 

How does the Kotor 1 droid model have glowing eyes, if there's the concern that the entire head would be glowing?

 

Anyway, thanks for the info. I guess there are limits to everything. :/

[DarthParametric 3,808]

The protocol droid? The eyes are separate meshes from the head. Same for HK-47. In HK's case they are keyframed to turn the glow on and off so you get the flashing during dialogue.

[Sith Holocron 2,514]

DP: If I recall correctly, you mentioned that MDLOPS would need to be updated to accomplish certain adjustments in model replacement. Would this eye glow topic fall under the same topic?

 

Malkior: following DP's advice, I wouldn't go crazy trying to add an eye glow. Try the brightness suggestion and see where that takes you.

[LiliArch 115]

Hm.... I might have an idea, but it has limitations too. Do I recall correctly about droids, are they only trimeshes or is there skin nodes also?

[ndix UR 219]

C_ForDrd is mostly trimesh but contains 3 skin nodes. C_DrdProt is just trimesh. (both contain dummy nodes also, technically)

[LiliArch 115]

Dummies don't count, it's skinmeshes I'm having issues with. All right, I'll try some sorcery and see what I can do. No promises, though.

[DarthParametric 3,808]

DP: If I recall correctly, you mentioned that MDLOPS would need to be updated to accomplish certain adjustments in model replacement. Would this eye glow topic fall under the same topic?

MDLOps is borked, yes. So is KAurora for that matter (albeit in different ways). It has nothing to do with self-illum/glow specifically, the problem is that you can't compile functional models for many/most droids, amongst other things. In this instance you'd need to split out the eyes to new meshes, thus you'd have to compile a new model.

[Sith Holocron 2,514]

I figured it would be something like that. That's why I pointed out that the glow wasn't necessary. However, it might be interesting to see what these folks come up with - now that a few more people are in the conversation.

[ndix UR 219]

Here's a glowing eyes version of the model for anyone to use as they see fit. It can also be bump-mapped, if you're so inclined. I did one for mine.

 

C_ForDrd-model-only.7z

 

In case anyone looks at it in detail, you may notice that there's a new head2_g mesh in addition to the new eyes_g mesh. If you've done a fair bit of modeling, you may have seen this weird thing where some part of a model's shadow seems to extend to infinity (often towards the center of the screen)... I started to get that when I made the eyes mesh a child of the head_g mesh (necessary to get eyes_g tracking w/ the head in all the animations). The only solution I could come up with was to make a full copy of head_g (head2_g) and make it also a child of head_g (position 0,0,0). Then I made head_g render 1 shadow 0, while making head2_g render 0 shadow 1. That worked. Yay. I actually used the vanilla head_g mesh for head2_g, instead of the 'eyeless' head_g mesh from this model.

 

I tried a number of other things that didn't help at all, including leaving the head_g mesh pure vanilla. The problem definitely came from adding a rendered child to head_g. Maybe someone will figure out what makes that happen sometime... I assume we will one day be able to fix the compiler to avoid that workaround, but it works for now (I think).

 

Actually, while I'm here, feel free to use my proto-height-map for anything you want as well. I've done about 20 normal maps for this model (none of which I'm that happy with), generally using this one as an input:

Thanks for all of your assistance, ndix UR!

[Malkior 477]

So, I .. don't know how to install your model files into my game to replace the default model. 

 

What I've done to test it was to change an existing UTI (Terena Adare) and view the results, but for some reason it's still using the old (non glowing) version. 

[DarthParametric 3,808]

Just extract ndix UR's C_ForDrd.mdl/mdx into your Override folder.

[Malkior 477]

Wellp it seems I was using the wrong Override folder

 

After re-extracting it, I keep getting intermittent crashes.. It could be a formatting error or the program simply isn't capable of running the extra geometry or edits. The crashes are "contained" by re-extraction, but after trying to leave the room upon seeing the droid, it crashes and continues to do so if I try to reload the level.

[ndix UR 219]

Interesting. Can I ask what level you are seeing this in? Is it something testable on my end?

 

I can upload another simplified model without the extra geometry (I forget if I also made it bump mappable, but if so I will take that out too) to test also. Probably tomorrow sometime.

[DarthParametric 3,808]

I can manage to transit in and out of the cache on Dxun without crashing, which is where I took those pics. Could be an unrelated issue.
