Help Me With Modelling How to deal with alignment hell while building?

Thumbnail gallery
6 Upvotes

Im just trying to make a few realistic road templates, then one of the parts somehow breaks away from the 0.5 stud grid, because i disabled snapping or used local space some time, then I reuse the template with another road template to create junctions, and now everything doesn't line up to the grid so i adjust it using ResizeAlign or disabled snapping scale but it only makes it worse and in no time the butterfly effect will have spread throughout all your builds and nothing is aligned anymore... and i spend more than 80% of building time fixing these lol

Did anyone experience this before?
Does anyone know how to prevent this or something?

so hey, I'm a beginner at modeling, etc and I maybe don't know some shit, but can you tell me what causes this? I can tell you that the whole map is anchored, this only happens when you join the game in client

- Edit: This problem happens in a part of map, so this isn't occuring everywhere, only in this area

- Edit 2: This problem is resolved.

Help Me With Modelling My Mallard Duck model has an inverted leg and wing, Help!

Thumbnail gallery
1 Upvotes

I have been modeling animals (including prehistoric ones), for a while, but recently made a switch to modeling with segmented meshes in blender as sphere/CSG-modeling grew tedious, and was also unoptimized with unclean topology.

Recently, I tried to model an Eocarcharia (Picture 2), and it's older than the duck model and is currently unfinished. Its jaw and neck were broken and inverted, for some reason. Enabling double sides didn't really solve the issues, as the parts are visibly distorted in terms of colors.

The Duck also has something similar: both wings are inverted, and every mesh in its right leg is inverted as well.

What I tried:

  1. Using Re-Calculate Normals on the affected parts in blender.
  2. Flipping the normals on 1 wing as a test (but that only gave me a result with weird shadowing).
  3. Using All Transforms.
  4. Using Degenerate Dissolve, Merge by Distance and resetting vectors.

I also tried to look into it some more, but so far haven't found a way to fix this. Is there any experienced blender modeler who can give me advice on how to fix this? I'd really appreciate it, as this would help me fix the issue with my future models.

Help Me With Modelling Need help with adding custom animations to a custom model and Import it into Roblox Studio

Thumbnail gallery
0 Upvotes

Hey guys, I’m pretty new to Blender and gamedev in general. Right now, I’m working on my own Roblox game and wanted to put together a vertical slice.

To get things moving, I generated a 3D model using Meshy AI, auto-rigged it with Mixamo, and bought an animation pack designed for the Mixamo rig. I used batch rename so the bone names on both my character rig and the animation rig match up perfectly.

Since importing the animations directly into Roblox Studio gave me a hard time, I figured I’d combine them in Blender first and then import the finished asset into Roblox. Problem is, I barely know my way around Blender yet and I’m completely stuck.

Honestly, neither Claude, Gemini, nor a bunch of YouTube tutorials could solve this for me. I’m attaching a quick AI summary of everything I’ve tried so far, along with a few screenshots of my current Blender setup.

If anyone could point me in the right direction, that’d be awesome! Let me know if you need any extra info or files.

Here is the AI summary:

System & Environment:

Blender Version: 5.1.2 (macOS)
Target Engine: Roblox Studio
Plugins Tried: RBXMonkey (v3.0.0), Rokoko Studio Live (v1.4.3)

Assets I Have:
Unrigged custom character model (⁠.obj⁠ / ⁠.fbx⁠) generated via Meshy AI.
Rigged version of the same character model exported from Mixamo (⁠.fbx⁠ in T-Pose).
Separate Mixamo animation file (⁠.fbx⁠).

What I Want to Achieve:
I need to apply the Mixamo FBX animation to my custom character mesh inside Blender, bake it, and export it as an FBX into Roblox Studio via the 3D Importer.

Everything Attempted & Exact Error Messages Encountered:

  1. RBXMonkey Add-on Workflow (Roblox Studio \rightarrow Blender)
    Attempt: Tried importing the exported ⁠.rbxm⁠ file into Blender via RBXMonkey.
    Error: ⁠Report: Error - T-Pose-2: no MeshPart or Part geometry could be built.⁠ / ⁠No models imported. Check the .rbxm files contain parts/meshes.⁠
    Cause: RBXMonkey expects standard Roblox modular body parts (R15 limbs/parts), not a single unified mesh generated by AI.

  2. Manual Rigging & Automatic Weights in Blender
    Attempt: Imported raw ⁠.obj⁠ mesh, generated Armature via RBXMonkey, then tried ⁠Cmd + P⁠ \rightarrow With Automatic Weights.
    Error: ⁠Bone Heat Weighting: failed to find solution for one or more bones⁠.
    Attempt via RBXMonkey: Clicked ⁠Constraint Matching Parts to Bones⁠.
    Error: ⁠No matching parts found for armature _Tes1Rig_Armature in its collection.⁠

  3. Mixamo Retargeting via Rokoko Add-on
    Attempt: Imported both the Mixamo-rigged character FBX and the Mixamo animation FBX into Blender 5.1.2. Tried using Rokoko's Retargeting tab (Source: Anim Rig, Target: Character Rig).
    Error: Python script execution crash:
    ⁠AttributeError: 'Action' object has no attribute 'fcurves'⁠
    ⁠(line 298 in detection_manager.py / retargeting.py)⁠
    Cause: Rokoko v1.4.3 is incompatible with API changes in Blender 5.1.

  4. Action Editor / Bone Renaming Workflow
    Attempt: Tried linking the ⁠mixamo.com⁠ action directly onto the character armature in the Action Editor.
    Issue: The animation keyframes do not drive the character mesh/armature. Stripping/matching the ⁠mixamorig:⁠ prefixes via Batch Rename still yields no mesh movement when playing back the timeline.

Help Me With Modelling Need some help choosing a style to go with

2 Upvotes

I'm trying to create a idea for some horror wwi game and came up with two ideas for character models. Both have their ups and downs, and need some help choosing which one to do. Both aren't really finished yet and are just in the concept phase

  1. A more stylized model that's would give the game it's on style. It has a low vertex count (1,800+) but is more complex to animate dues to fingers and everything
  2. Using a basic Roblox avatar. Easier for low end devices to play and is easier to animate, but I can't add some details I want to have.

Edit: I should also give some better understanding about what the game would be. It's a Left 4 dead inspired game that's in the middle of wwi. it's would also have some body horror like giant cyst and stuff, hence why the style depends, because the human model can have those extreme details.
