❀ DoN's Dynamic Mesh Effects ❀

[VSZ]

When i shoot anemy, i see the stroke at same position, how i can do like in video with batterfly please?

To preface, have you seen the Quick Start Guide page and the Preparing Your Mesh for Painting steps already? There are certain mandatory setup requirements for skeletal meshes which those pages talk about.

Assuming you've setup everything up as per those docs, can you share the following:
1) Screenshot of your material (just the part with the Don Mesh Paint UV1 node is enough)
2) Screenshot of how you're calling the Paint Stroke node
3) If you have already setup the Physics Asset and the UV1 special UV map for your character (as per the docs), then a screenshot of those will help as well.

One useful debug technique is to bring your character into the example project and replace the demo character with yours. That will allow you to focus on verifying just your character's setup first.

Thank you for you quick support!

"Skeletal meshes: A lightmap UV is compulsory for skeletal meshes in this workflow. So in addition to your regular UV map (UV0), you will need to create a simple lightmap UV on UV1. You will need to ensure that every part of your mesh (per-pixel) has a unique coordinate in the lightmap UV you’ve created. Now you should be able to use Don_Mesh_Paint_UV1 to paint without any issues."

And

"3) If you have already setup the Physics Asset and the UV1 special UV map for your character (as per the docs), then a screenshot of those will help as well."

How i can do this? please, thank you

The result with this 2 screen is the first screen with the character, with "blood decal" all the tim at same place

If you haven't setup the character's UV1 map or physics asset there's no point testing any further, the results will invariably not make sense.

For setting up UV1:
1) Go to your favorite DDC - Blender/Maya/max etc.
2) Create a new UV map for your character in the UV1 channel (instead of the usual UV0)
3) Unpack all faces onto unique UV islands. You can do it any way you like, the only golden rule is that each vertex/face needs to occupy a unique spot on the UV Map. i.e. No overlapping faces, so just like a Lightmap UV.
4) Export your character back into UE4 again, now the "Don Mesh Paint UV1" node will work because it has the right UV data to work with

For setting up physics asset: Follow Epic documentation on physics asset creation/etc.

The precision of your Hit Result determines the precision of your paint decal placement, so you need a physics asset that very accurate; it should envelop your character as tightly as possible to provide good results.

You can open the demo character's UV1 map (in Persona -> Show) and its physics asset to see how both are setup.

The 2nd UV like Lightmap i do it, and the physical asset it's like this: (firts img)
But nothing, i dont know why doesnt work ç__ç
Spawn the decal black, and every time in the same position.. (second img)

[vinstriano]

Wait, without brush decal texture and brush render material works!!!
Now i understad why you say physics asset, have a little problem on the chest when i shoot it. but leg and arms looks god!
Can you help me for the decal of blood please?

[vinstriano]

Please, can you make a video tutorial for third person project for decal on character? For me works now but only with circle brush

[vinstriano]

I make a good physics asset and good lightmap but nothing, decal spawn every time at same place, black and big one, plase can you help me?

Hi eddiescofield , can you email a small repro project to support@drunkonnectar.com with your username in the subject? It will probably be quicker that way. If desired, you can substitute this particular asset with any dummy character that showcases the issue.

PS: I need 24-48 hours to respond to messages as I receive a high volume of email. Sunday/Weekend correspondence will necessarily be delayed.

Yes i know this, no problem, sorry for the spam, really. But i love your plugin and i don't know why decals doesnt work, i follow step for step the guide in website...
Anyway ok i send you the project. If i can give you advice, do a little tutorial on your channel youtube, for simple material works for decals on mesh with a simple project like first person or third person. So, thank you so much for the support!

No problem - Just let me know when you've sent it over. I don't need your main project, a new third-person project with any dummy asset that showcases the issue is sufficient.

Based on the resolution we attain for this issue, I'll see if the tutorials need to be improved in some way or if a video is needed to complement the existing docs.Thanks for your feedback.

4.21 update: I've received confirmation that the decal size issue mentioned in this post is fixed with the provided patch. 4.21 update will be submitted soon along with this bugfix!

[vinstriano]

YES!!! Thank youuuuuuu!!!!!

[VSZ]

YES!!! Thank youuuuuuu!!!!!

Hi, sorry for the confusion - I think you misunderstood my previous message. The decal size issue I mentioned is a completely different issue that was affecting other plugin users (see that post for details). That fix will not help your issue in any way at all.

Yours is probably a setup issue of some kind, so I still need the sample project I asked for so I can fix it for you and update the tutorials if deemed necessary.

Please let me know when you've sent the sample project over or if you need more information on what is to be sent.

[vinstriano]

Ahn ok i tell you when i send you project

Ahn ok i tell you when i send you project

Thank you. Here's a few other things you can also try while you're preparing the test project.

1) Try using a decal texture from the demo project instead of yours, to rule out issues with the decal texture.
2) See if replacing your material with one from the demo project works to rule out issues with your material (you can pick the character material from the 2nd example for decals)
(...or replace the demo project's material with your own)
3) Import the demo character into your project and see if your decal setup works on that model..

The test project will be useful to quickly diagnose the issue though.
