The file was initially made on Sketchup Pro on Mac. I transferred to my PC for rendering on Sketchup Make and VRAY 3.6.
The file was extremely large and slow despite only containing basic geometry and minimal imported elements. I purged the file, gaining about 10mb, I then slowly went through deleting elements and purging to locate the problem and eventually had nothing left.
I zoomed extent, turned on hidden gemometry and deleted everything. The outliner contains nothing but the file name. VRAY has no textures or lights, etc. I did a final purge. Yet the project is still 360mb.
If I copy and paste the contents to a new sketchup file it is 30mb.
I really dont want to have to transfer to a new file and lose all the views and potentially VRAY information.
Materials is likely to be the problem. I did add some high res textures via VRAY. But I also purged VRAY, which is empty. Is there somewhere else I can locate materials in the project?
Thank you Dave. Through those steps I have located those images on one of the layers.
I had incorrectly presumed that hidden geometry would have exposed all geometry on all layers, and I had not fully gone through each layer and selected all and deleting.
The base image from which I made my geometry has been weighing the project down the whole time
Ah… The penny drops. Turning on Hidden Geometry doesn’t display content that is assign a tag/layer which is invisible.
Note that geometry and other entities aren’t on layers in SketchUp. Layers (tags now in 2020) are assigned to objects. All raw geometry should have Layer 0 assigned to it (or be untagged in current terminology) and only groups, components and other objects should get other layers/tags assigned.
