In a collaboration from Blender Daily and the Blender Bros, we created a video course with the goal to share the most valuable tips we collected throughout almost a decade of combined Blender experience. In the end we came up with 497 useful tips and 12+ hours of content. They are all in video format and roughly 1-5 minutes long.
We have an early bird special going on. If you buy the course up until Monday you'll get 20% off the regular price with the coupon code "497" at checkout! You can get it on Gumroad and on the Blender Market.
