Texture & Asset Upgrades

[d-wasserman]

This is a general comment that I would appreciate any donations from individuals using this rule of of open source models, textures, and assets to improve the visual quality of the rule. Also any recommendations can be left as a comment on this issue. Some general elements that need consideration for an overall are:

• Removal of stamp based textures to only use full PBR materials. This means stamps would be replaced with inserted "stencils" for bike lanes, turn lanes, bus lanes, TWLTLs, etc.

• [x] Bike Lane Symbols (in Dev Branch)

• [x] Bike Lane Arrows (in Dev Branch)

• [x] Bus Lane Letters (in Dev Branch)

• [x] TWLTL Arrows (in Dev Branch)

• [x] TWLTL Transition/Painted Taper (Similar to that documented here) (in Dev Branch)

• [x] HOV Symbol (in Dev Branch)

• [x] Turn Lane Arrows (Multiple- Right, Right Through, Through, Left Through, Left, All) (in Dev Branch)

• [x] Carshare Only Symbol (in Dev Branch)

• [x] Bus Stop Letters (in Dev Branch)

• [x] Stop Symbol (in Dev Branch)

• [x] Crossing hatch (in Dev Branch)

• [x] Angled Parking (in Dev Branch)

• [x] Bike Buffer Paint Marks (In Dev Branch)

• [x] Micromobility Parking Spots (in Dev Branch)

• Acquisition of PBR textures for the bare minimum of:

• [x] Painted Asphalt (White, Yellow, Green, Red, Blue - Edits were made in GIMP to the selected Asphalts below. )

• [x] Asphalt (Black or Black-Grey)

• [x] Concrete (Sidewalks)

• [x] Brick/Stones (Sidewalks/Crossing) - Multiple (1,2,3,4,5,6)

• [x] Curb/Planting Borders (Edited Concrete)

• [x] Dirt (Ground)

• [x] Grass (Plantings)

• [x] Rumble Strips (Use Asphalt for now)

• [x] Rail/General Metal Textures (Rails)

• Acquisition of New Street Assets - current CityEngine upgrades suffice for now. Identifying unreal replacement actors/assets might be a good way to address this generally instead of keeping them with the project.

Notes:

• Concerns over size- as I mentioned these upgrades to outside parties, there were concerns about the size of these changes. It could increase the repos size enough it is harder to download. As it stands the repo is ~130 MB, and the upgrade max target is ~250 MB. This is an increase in size, but not massive. Experiments with GIMP exports of JPGs show that reducing the quality of the export to 90-95% can decrease the size of the file substantially. This will be used strategically to make sure PBR upgrades can be done quickly and efficiently. After that if someone exports to Unreal or other platform, at least material replacements will be substantially easier.

The most recent release has upgraded PBR textures for asphalt and paint, and stencils. Sidewalks and medians will not have PBR for a while, but will be revisited when CityEngine supports materials. This will be closed for now.
