After some more testing and checking with the older model. There old char model had multiple materials too, but spread out amongst modular clothing. Body And head separated, both get 1 material each. Shirt, jeans, jacket, shoes all have their own single material as their own separate models… also a skeleton mesh underneath, 7 materials being painted total, but in a loop with paint stroke from model to model.
Current model is merged, but with less materials total, 4-> head, body, arms, legs. But combined as a singular model. And produces lag spike per stroke.
Not sure why it’s such a performance difference when doing multiple paint strokes separately, than doing one that covers multiple materials…
Seems there needs to be a way to spread the out the stroke between materials or something… like over the span of 0.125 seconds or something. I’m not really cpp savvy. But I’m not sure if we can merge materials further without losing out on high quality modularity with our models. We were at 13, but now at 4-5 but the spike is still too noticable.
