Car Donut SmokeTrail- Week 4
A reminder of the goals for this week and a synopsis of whether they were reached.
Goals for Next Week are as follows-
Render Farm test - ✅
Add Micro Solvers to the smoke if found needed - ✅ Were found to be not needed
Correct the shape of the Small Sim - ✅
Correct the shape of the Large Sim - ✅
Correct Starting and ending movement of the Car - ✅
Finish Set Dressing - ✅
Lighting - ✅
Create Skid Marks - ❌
Here is the most recent test render of the Car with smoke.
A simple lighting setup test within the scene to confirm that it doesn’t overpower the focus of the car.
To Speed up the process in set dressing, a hanger was used as a mimic to the environment that some Car commercials use as a background, and as to hide more environment than needed. The hanger was made and modeled by Eiji-Kun on CG Trader.

Continuing from last week, I continued to work on the shaping of both the Large and Small simulations. The Small only having 2 more tests of shape, while the Large had an additional 9 tests. The last test pass for each is the current decided on simulation.

An update to the path the car follows was done to correct the starting and ending angle of the car.
Updated Car Pathing
I was able to confirm with an initial test that the Simulation and textures were readable on the farm. This was made possible by separating the parts of the car into groups prior to adding materials.
Farm Render Test with textures- Incorrect shading of Smoke
Goals for Next Week are as follows-
Make the smoke not appear till a few seconds in
Any Additional comments made by supervising Professor
Create Skid Marks - Added effect to play realism to the eye
