Hi! Im trying to subd a sphere, how do i get rid of this?

Don’t use a normal sphere. Instead grab a cube sphere.
Add the default cube, subdivision surface modifier (to 3 or 4) and than a cast modifier set to sphere. Duplicate the cast a 2 times to make a perfect sphere. Now you can apply all the modifiers starting with the sud-D.
After that you can freely add more subdivisions by using another subdivision surface modifier

There’s also an add-on which adds the specific cube but I forgot the same and you could subdivide the cube and search (F3) for to sphere

okay, thanks so much!

#

and how to make a glass ball?

#

like that i could see things inside

#

like make this a thin glass thing

#

similiar to this, but the drop looks way different

#

the drop

#

also same material

You use the glass shader and set the ior to smth between 1.45 - 1.5.
Then add a solidify modifier if you want air inside the drop, otherwise it’ll be solid glass.
You can use a mix shader and use both, a glass and transparent shader to control the glossy effect.
Another thing that might be worth mentioning is that you can use a layer weight (facing) node for the mix factor to great “thin glass”

this is what i used

Volume absorption should be used to change the Color (which can be really heavy for your pc) and the roughness slider is fairly sensitive so start with 0 and maybe go up to 0.05

#

where do i put volume absorption?

#

also why is it blurry?

First of fresnel gives weird results especially if the back facing areas are visible. So try to use facing instead.
0.5 roughness for the glass is way too high and I don’t think you need an additional glossy bsdf. It adds more reflection which is most often undesired

# deft plinth its not doing anything

First fix the stuff with the glossy shader. Try to use a normal glass shader with a 0 roughness and a volume absorption. Nothing else.
Give the absorption an extrem Color. That way you can tell what’s happening. Increase the value to something that you like. After that adjust the Color, than change the glass roughness and after that’s done you can play with a mix shader.

Atm you are using so many things without knowing what they do. You can’t properly measure something if you have like 5 variables

im really lost

high brook
#

Set the roughness to 0 and use cntrl a to apply all transforms

#

Also make sure the right material is applied

oh, worked, thanks

high brook

👌
Glad I could help. And always try to minimise variables. I sound like my physic teacher but I gotta say the he was right.

no like, you don't NEED two cast modifiers.
0.5 fac + 0.5 fac = 1 fac
at least, they SHOULD be the same

They are not but the one thats set to 1 is closer to a perfect sphere. Not visibly but you can tell when using a really high subD amount and a high res sphere that intersects. So note for me, use 1 instead of 2 times 0,5 polysmile
