I converted the texture.png to texture.jpg which was only 3+ MB and edited the. The mtl file references the original texture file used by my dae model - which was a png file of 49+ MB. It provides a set of tools for editing, cleaning, healing, inspecting. When saving my model as an obj the file size reduced from a dae at 74+ MB to an obj at 26+ MB with the creation of an. MeshLab the open source system for processing and editing 3D triangular meshes. Which isn't a simplication if you are looking for a menu entry beginning with Q. "Filters → Remeshing, Simplification and Reconstruction → Simplication : Quadric Edge Collapse Decimation (with texture)" "Filters → Remeshing, Simplification and Reconstruction → Quadric Edge Collapse Decimation (with texture)" the version of Meshlab you used is Meshlab_64bitv1.3.3 - the latest version is Meshlab 2016.12 and the menu entries are slightly different, which initially stumped me - as there is no entry in Meshlab 2016.12 of I’m new to 3D modeling.Thanks James for the article - this helped me successfully to reduce my image size - however a couple of pointers for anyone else wishing to reduce the file sizes for uploading to Sketchfab and avoid the minor difficulties I encountered :-ġ. His statement concerns me and that my approach here is up the wrong tree. Another post in this SketchUp forum from a SketchUp employee suggests that numbers in the millions will create problems. My model in MeshLab has 1,082,867 vertices. With MeshLab, you can do some of the housekeeping tasks you need to do to take your SketchUp asset model and. Apparently Blender provides some sort of alteration or filtration that makes the model more pallative. This tool is your 3D-geometry studio on a budget. I even saw a posting in this SketchUp Forum suggesting importing the Collada file into the open-source editor Blender and then exporting in Collada format and then importing into SketchUp. SketchUp just hangs and does not recover (even if left running overnight). I have tried exporting my model from Meshlab in Collada format and then importing into SketchUp. I export my model from ColMap into the open source MeshLab and it looks great. I’ve some samples of my models at: Work in Progress Samples - Court/Chemeketa Shadow Analysis for State Street Project adjacent to National Register Historic District Court-Chemeketa - Album on Imgur I think I have made good progress on this front and feel I can create such models of houses. If I can perfect a workflow that produces satisfactory results, I’d like to model the homes adjacent to the commercial district so the Shadow Analysis afforded by SketchUp can be more realistic. To that end, I’ve been experimenting with ColMap creating 3D models of my house and garage. I want to be able to create 3 dimensional models of a few houses and place the associated house over its footprint to make the model more attractive and simulate a view one might see from the sidewalk. This give me the ability to create 3D blocks and then see how the shadows fall. I’ve been able to import shape files for the tax parcels and the the building footprints. I’m trying to create a Shadow Analysis model for the City of Salem, Oregon, in conjunction with their consideration of a downtime plan for a commercial district that is adjacent to a Nation Register Historic District that contains old residential homes.
