Procedural hydrogels in Blender

This is a quick tutorial on how to create a customisable hydrogel illustration using geometry nodes. NOTE: we will only consider simplified models of hydrogels; we won't look at showing any rigorous internal structure of the polymer chains and how they are cross-linked.
Make sure you have Blender 4.0 or higher:

If anyone was like me and had an opaque hydrogel at the end of the video, remember to change the render engine to cycles! 😂

[@ryomizutagraphics]

Woops, sorry! Should’ve said - I usually work in Cycles

[@jamiefinn4438]

Actual life saver....

I was struggling for 2 hours. thank you!!

[@arezoosdp]

Thank you for this video. it was very useful for me

[@sciart1512]

Fantastic! Thank you so much!

Hey .....i followed all the steps as you have mentioned but i am not getting transparent gel with these polymer .....even polymers are inside the gel ...but when i am giving color to gel its not becoming transparent ....
I am getting my mistake please help me it's urgent

[@ryomizutagraphics]

Make sure you’re using Cycles, not Eevee

[@shinugupta1445]

I don't know where i have choose this cycle engine

[@shinugupta1445]

I am not pro in blender i am using first time ...

[@ryomizutagraphics]

Under Render Settings

[@shinugupta1445]

Thankyou very much......also can you tell me ...that how i can export this figure in PPT ...i am exporting in .glt form but it is not coming exactly like this.....please suggest me how can i export this

How do you add more than one polymer within the hydrogel?

[@deylightmedia3266]

by making another copy of the same group and randomised start and end

[@user-fp7sq2qm6y]

Hi @deylightmedia3266, thank you for your response. I was wondering whether the same procedure can be followed as to addition of probe particles within the hydrogel as that followed in one of your other videos in making AuNP? I am making Render engine Cycles.

[@ryomizutagraphics]

@@user-fp7sq2qm6y Yes, duplicate the distribute points in volume, instance on points. Create a AuNP (e.g. a Points node + Set Material with a gold material), plug into the instance on points. Join that with the hydrogel with a Join Geometry node
