BETTER PERFORMANCE in Blender with the Decimate Modifier!

In this video, learn to use the decimate modifier for Blender to reduce the size and complexity of objects to improve performance!

Often, we'll use models inside of Blender that are just too complex - they have way more faces and vertices than they really need, which can really hurt your model performance on your computer.

This modifier gives you an easy way to reduce the number of edges/faces/vertices in your model!

Hi everyone! Let me know what you think about the decimate modifier in the comments below! :)

[danieljolani]

This is actually such an under appreciated simple step to stop blender crashing...while everyone is focused on cutting down the esthetics...ur chopping down the base structure...well done buddy!

For game models to get the most optimal results use planar, with the option that preserves your uv seams. Then select an angle that gives you an acceptable amount of detail. Place a triangulate modifier after.

I notice every time I need some Blender info I end up coming back to you. Concise and clear, thank you. I was panicking about what I was going to do with my model that caused Blender to slow down severely. I used the decimate modifier and brought it down where it still looked good. Now I can even use duplicates of the object in my scene. Thank you, thank you, thank you!!!

[wendysbrian]

Whoah that PLANAR method just stopped me from ripping my hair out man. I was stuck trying to do UV work on a model that had waaaay too much topology, this is way better. You are a life saver. THANK YOU!

[penelopesaladfingers]

i love you for this - it made staying up till 3am fretting about a messy 2m triangle mess of a scan - wondering how i'd ever get anywhere with my pc moving at the rate of a snail, well worth it, thank you, your tutorials are spot on.

[Kimmy_Nami]

I just made a 3D scan for the first time in my life, and was figuring out how to make it smoother. Thank you for your tutorial!

[xtremegamemaker]

Thanks bro.
I had downloaded a terrain model for my game in python and it had so many faces even my rtx 2070 super couldn't handle it. This saved my life (and my computer)
today.

Explaining the plane modifier saved so much time and effort on my avatar.

[Cferg]

I started using Blender in the last month. You’re videos are a wealth of knowledge.

[stevejones]

What a completely clear and easy to follow and understand tutorial!

[aliceleblanc]

Thank you for explaining all 3 decimate options! Saved my life! :D

[clairestrickland]

Thank you, really helpful. My mesh was so huge from Rhino 8 shrinkwrap (me not really thinking about what settings I was using), so needed to jump into a quick and helpful decimate tutorial. Thanks so much! My first time using Blender.

[kevindomara]

Thank you so much! This is exactly what I needed. Very clear and understandable. I watched 2 videos before this from other people that I couldn't understand.

[mysterious_monolith_]

That was ABSOLUTELY BRILLIANT! Thank you! I didn't think a newb like me would be able to understand this but I do! You explained it so clearly.

[Deleted]

Do you not know who frecken helpful this is! Dude thank you! I always use subdivided to make my models but everytime I use it to animate it the bones never actually connect but because of this not only the model doesn’t change but it still looks nature! So thank you! Now my computer runs easier and faster, truly thank you!

[raccoonicorn]

this has helped me so much with Importing my avatar onto the Quest. Thank you!

[WalkCareful]

Thank you CG for the best explantion of how to get vertex's numbers down, these other youtubers beat around the bush! you kept your vid/instructions simple and short, this helped alot man big ups

[donsorenoelchapogringo]

This is really helpful for game assets, especially creatures which are difficult to edit after subdivision surface and triangulation has applied.

I'm putting my first model for sale up on Blender Market. It just struck me that I'm going to need to do some optimisation. First time in about ten years with Blender. 😅This was a helpful overview. Thanks!
