veflt.blogg.se - Zbrush dynamesh not working

Subdivided again the meshes are 2.6 Mill, 3.6 Mill and 3.6 Mill. Overall colour and detail is better than before, although still not as good as I would like!īut I think with Sketchfab surface effects it should look ok. The model which was exported with polypaint from Zbrush appears to have no vertex colour in MeshLab! But when I toggle the wireframe icon on the top menu, it becomes visible.Ĭlose inspection shows that the colours are indistinguishable, but the placement does vary very slightly between the MeshLab ‘Transfer Texture to Vertex’ process (01Subdiv) and the Zbrush ‘Create Polypaint from Texture’ process… but this is not important for this project. The ‘Transfer Texture to Vertex’ filter works well on the model which was exported without polypaint from Zbrush.

To sort this out, toggle the wireframe icon on the top menu and change Colour Mode to Mesh on the right menu. Wireframe displays by default and the model appears black. In MeshLab, the Zbrush exports look different because of some display qualities. So I export models from Zbrush before and after applying colour to the vertices, so I can compare results in MeshLab. Also the range of colour/tone on the surface may be greater per square cm.Īfter subdivision, the brown pot models are now 660K, 900K, 900K approx. So this isn’t that different, although the surface area and volume of this pot is much greater than that of the grey or yellow pot, so perhaps that’s why the resolution is so clearly insufficient. Just checking previous projects: upright grey pot was 557K polys, side view 300K. The aluminium birds from A Flutter Of Birds tended to be much bigger (around 2 Million) but they were more complex objects in terms of gross geometry. The meshes are surprisingly low res: 220K, 300K and 300K approx. Or maybe I should try doing this step in both softwares to see if one is better than the other? So now all the meshes are in Zbrush, I’ll subdivide them and then apply the texture to the vertices in Zbrush instead of MeshLab. It’s so satisfying and reassuring when the texture corrects! There’s probably a quicker step sequence, but this works. Texture Map (Right Side Menu) > Click on texture square > Select Texture > Texture will correct itself.

Texture (Top Menu) > Select texture > Flip V.

Texture Map (Right Side Menu) > Click on the black square > Select Texture > Texture will come in upside down.

Texture upside-down by default and therefore looks like garbage Use Flip-V on each, as the textures come in upside-down by default. Annoyingly, the OBJs come in minus their textures which must be imported separately and applied to their respective meshes manually. Zplugin > Subtool Master > Multi Append > other 2 OBJs. Then go into MeshLab and continue as usual. The mesh res is too low to hold the colour well on the base: MeshLab Align tool You can see the triangles which are the mesh polygonsĪ possible fix for this is to take the ReCap export files into Zbrush, subdivide (so that there are more vertices) and then transfer texture to the vertices (‘make polypaint from texture’). Untick False Colour tick Allow Scaling.įor the first time ever, I’m not happy with the resolution of the vertex colour of successfully resolved ReCap Photo models. I start with the two base views as the pot base contains some of the best markers. Next step is to use the Align Tool – Point Based Glueing. 3 partial models in MeshLab, with vertex colour applied Import one at a time into MeshLab, each time using the “Transfer Texture to Vertex Colour” filter to transfer the colour data into the mesh vertices. Underside removed – inaccurate so not useful The scanner kept losing tracking: it struggled with the exterior and couldn’t reach far inside the pot due to the very narrow neck.Īs usual I edit the models in Recap Photo to get rid of unwanted geometry (undersides and tabletop) and export OBJ files. I have no scan data of the inside of this pot as it was impossible to get a decent scan. (The Meshroom model was less successful than the Recap Photo model.)

Darker side of photographers’ lights model made in Recap PhotoĪs even lighting is better, I will go with the 3 Recap Photo models made from the photos taken with photographers’ lights.1 Meshroom model made using 138 photos (upright / with lights).6 Recap Photo models made using 100 photos for each.3 sets of photographs (upright / side / other side) taken with photographers’ lights (approx 140, 100, 100).3 sets of (approx 100) photographs (upright / side / other side) taken with natural light.Data assets I have collected for this model:
