Thanks :) really? that's a compliment to inpsire someone else, thank you, I never thought I would inspire anyone to also create underwater renders or animations, cool.

@@mrEC1987 question - are you using any kind of volume material (volume absorption, volume scatter, principled volume)? Because whenever I try that with real caustics the results are less than favorable

@@EvenEEvenII No, I actually don't use volume with the Blender shadow caustics since they don't work well together, it's because it is still not really supported so it causes weird artifacts and it looks wrong.

@@mrEC1987 I’ve developed a method to fix this. You have to move the volumetrics cube/object slightly *above* the sea floor. You could also slightly lift it above the creatures/other objects or you can just increase their brightness with a hue/sat/val node to make it look right.

@@EvenEEvenII It works? nice, I didn't know that trick.

It was using this way that this video shows but only using scale mesh operation script line of code on the vertices of the loop of edges in the middle of the object, you can use MaxScript Listener to get the right command line code by scaling or doing something in the viewport to get what you need (but some commands are not showing up in the Listener so then you would have to look up into the MaxScript help files which mentiones all command lines.

@@mrEC1987 eh yes but completly dont understand how to change shape

@@edgarprotsko1558 Basically it wasn't really changing shape, it was simply scaling the middle verts and since it was a low poly + mesh smooth modifier on top of it, it looked as if it was changing most of its shape gradually..maybe you can show me exactly where you are stuck at or the full code you are trying to perform and I will look into this (or I could try to find the scene file of the muscle sim and send it to you since I can't open it up with no 3ds Max installed)

Thank you very much, as far as I remember the trick was mainly to use a script controller (as I mentioned before) which is able to perform things in real time in the viewport...in this case it scaled out the middle edges of the muscle in real time using some ratio calculations I did which I completely forgot. BTW I managed to do a similar muscles simulation in Blender (the free 3D program) using Geometry nodes and soft body/cloth simulations and it turned out really nice, even better than this one since in 3ds Max I had no real solution to the skin of it that holds the muscle inside it and in Blender their cloth simulation after tweaking is able to act like a skin and it is able to contain the muscles with almost zero issues, also it allows me to even give weight distribution for the muscles which is a bit more realistic, I am more satisfied with hat I got using Blender but I am still working on improving it.

@@mrEC1987 Can you try to remember how to use script controller

@@mrEC1987 maybe this can help to remember czcams.com/video/GfoXWe7jGCo/video.html

What Blender version are you using?

Well I worked on it along time ago and I uninstalled 3ds Max which I ditched about a year ago and made the switch to Blender so I can't recall what I did exactly but it was something to do with making sure using the script controller that according to the distance of the two helper objects that are located at both ends of the muscle that it scaled the middle set of loop vertices outwards using soft selection as well...that gave the illusion of a muscle contraction and change of shape mechanism.

@@mrEC1987 you gave me hope and took it away from me! Hahahha no worries, man! Tha K you for explaining the workflow. I'll take a look at it!

@@Baarth_ Well sorry, maybe you can come up with something on your own hopefully and maybe even sell it, why not :) but yeah, at least I could recall some of it and give you a hint about how it used to work.

Cool :) glad I could help someone

Sorry, I don't really understand your issue, maybe explain it further to me, I might then be able to help you.

:) Thank you, glad I could help.

👍 Cool, glad I could help someone with this video.

Yes my friend, is amazing technique. I use your technique for a spaceship animation. For my documentary. Thank you. I am rendering now in Full HD so fast, without adaptive sampling because the denoise is remove all the noise. It renders with transparency background, so I can import in After Effects and make the spaceship fly! Very happy :D

@@daanthijssen1748 Cool, good luck and have fun with your project :) (this technique is not mine though, I just followed another tutorial's steps and created a simple how to short video for it).

No problem, glad I could help.

Ah, I see, I did not know this, thanks for your comment and insight on the issue.

Thanks for your interest, I only now noticed the comment (YT didn't show me it on my bell), I don't intend to sell it, I might give it for free one day but I've no time for working on it and I also ditched 3ds Max since then and moved on to Blender.

Saw your comment only now, well I worked on it along time ago and I uninstalled 3ds Max which I ditched about a year ago and made the switch to Blender so I can't recall what I did exactly but it was something to do with making sure using the script controller that according to the distance of the two helper objects that are located at both ends of the muscle that it scaled the middle set of loop vertices outwards using soft selection as well...that gave the illusion of a muscle contraction and change of shape mechanism.

Well, then sorry, these solutions are the only ones I know so far and they are good enough for me and most people I think, I'm still a beginner in Blender, I've quite a lot of things to learn but I think there is no perfect solution to this issue.

Thank you for watching 👍 Glad it helped.

Thank you, Since I created this a long time ago I barely remember how I made it but I think I simply used copies of splines from the pipe spline (that had thickness on) to create internal splines on a bit different offset positions and then I put a path deform (wsm) modifiers on blue cylinder objects (primitives) for each internal spline to make them move on these splines (with a simple spinner animation), then I exported the png images of their animation as a sequence of images to be used in Premiere, then in Premiere I used I think motion blur perhaps + some glow that I created using a copy of their nested animation with gaussian blur on it + a suitable filter to make it look like it is glowing.

@@mrEC1987Wow pretty interesting idea and good realisatio!n

@@mrEC1987 Thank you for your response !

@@vladyslavmorningstar :) thank you.

@@vladyslavmorningstar No problem, glad I could help.
