Can't Get There From Here
I thought that title was good as sometimes it's difficult to navigate MB3D pieces. It may only be me who has difficulty, I don't know. I Don't use the 3D navigator exclusively like many do. So it occurred to me that some of the pieces that I've posted parameters for may be difficult to tweak if you use the navigator exclusively. If you don't have any problems with the navigator, just disregard this journal, otherwise, read on.
My way or the highway...
Of course not. Everyone has their own techniques and favorite ways to explore. To think there is only one way to explore in MB3D is ridiculous. And I'm certainly not saying there is a best way either. What ever works for each of us should not be shoved off on others as the best or easiest way to go about things. What I'm discussing here will be how I go about it and how that might present problems to others if I happen to post parameters on a piece. Or perhaps you suddenly find that after adding a formula to your piece or changing some values in the formulas you are using, the navigator suddenly becomes uncooperative.
The way I tweak...
This is the way I work. I usually load up one of my existing parameters. I keep everything. I may post a piece that I had saved 5 or 10 different versions of before I was satisfied with it, so I have a ton of parameters to choose from. I do my main tweaking in the main window. Why? Simply because the view is much clearer and bigger. That's nothing against the navigator, it's just a simple fact. Minor changes of the values in formulas may not show up at all in the navigator. (I'm sure that is common knowledge) So because I see the details and formula changes better in the main window, I use it more for rotating and zooming as well.
But why, the navigator is so easy to use!
Yes it is. But it may be just as likely that suddenly after a few formula changes and tweaks, it quits working. I didn't use the navigator at all a while back because of this. A lot of people were stunned by that. Over time, I forced myself to use it and finally found most of the little tricks to get results with it. I know I've done a lot of really nice pieces but I still don't consider myself an expert with MB3D. I just don't know the technical stuff and may never learn it. So as I tweak away, I may rotate my view in the main window as well as using the move tool and zooming. All of these tweaks may mess with the navigator functions. I'm sure many of you have found at one point or other that this happens. You may just undo changes until you get the navigator to function again, or you may know other ways to fix the problems you have. The following is just one way to fix a particular problem that crops up.
The, "My back is against a wall" scenario...
That may be better known as the "I'm having a nightmare and the monster is coming after me and my feet are glued to the floor and I can't move" scenario. So you've tweaked away and go to the navigator and try to look around and a): either everything disappears, or b): you cant move. The "everything disappears" thing is easy to fix and I think almost everyone knows the solution. You just adjust the far plane setting (to a higher value) in the navigator. The "I can't move" thing, while a little time consuming, can be fixed as well. I only know of one way to fix this, some of you may know of other ways. If you know of other ways, please tell all in a comment in as clear and non technical way as possible!
So Mr. Genius, why the super glue?
Teleportation my friend! Somehow you have teleported inside your piece. You can't backup, (zoom out) walk forward, (zoom in) and often can't look side to side either. In other words, there is some structure behind you and you bump into it while trying to move, or you are actually right inside a structure that is holding on to you. For a long time I simply abandoned the navigator when this happened. So how do you fix this? One way is to cut your way out. (There may be other ways, but I only know this one way) It's kind of like opening a door behind you so you can back up. The neat thing is if you open that door behind you, it also allows you to move forward and side to side as well so you basically restore the full functionality of the navigator.
Trial and error, the story of my life...
Trial and error is not such a bad way to learn. It's time consuming but often the lesson sticks with you better. So let's cut away! So you are glued down in the navigator and can't move. The first thing you have to determine is what plane you are facing. I did a tutorial a while back that covers the basics of cutting (Mandelbulb3D Tutorial 3) so I'll not go over cutting in too great a detail here. So assuming no cutting plane is selected, click on the cutting tab and select the x,y or z plane. I start at the top or the x plane. You select the plane by clicking in the empty box and a check mark appears. The x plane is now cut at 0.0 (zero). Click calculate 3d and then RELOAD your parameters in the nav window. See if you can navigate. If no, then change the cut value in the x plane up or down. Go for a large value to shorten this trial by error solution. So lets use 4 as a value. Click calculate 3D and RELOAD parameters into the nav window. See if you can navigate, if not, repeat above changing the value to -4. Reload parameters and try navigating again. Usually if 4, 0.0 or -4 doesn't fix the navigating problem, then we are working on the wrong plane and we would move on to the y plane and go through the same trial and error.
Hey bud, you fuxored my piece!
Sorry about that! So yeah, by the trial and error described above we found the plane we wanted but our piece is totally destroyed because we cut it to ribbons. Well that's because we're not done yet! Let's assume we found that we are looking at the y plane and it is now cut at a value of 4.0. It looks totally different because we cut too deep. We can navigate now but we went way past the nice area we wanted to explore. All we have to do now is fine tune the y cut value. Assuming we are at 4, lets lower the value to 3, then 2 and so on (clicking calculate 3d between each change) until we get back to the view we had before cutting. Let's say we have to go all the way down to a -1 value on the y plane cut. Now our view is the same as before we started, but wait! Navigating is broke again! So we went a little to far. Try -0.8 or -0.6. You have to fine tune to make this work and keep the same view. You may end up with a y plane cut value of -0.17 or anything. It takes time but once you do it a few times it's fairly quick and easy.
Why bother, you're wasting my time...
Well sure, it's just something I do to get the most out of a piece. If you abandon some parameters you can no longer navigate, you might be missing a real beauty. By the way, if you can't navigate a piece that is already cut, then you just have to adjust the existing cut value to fix it. The bad news is that this cutting trick sometimes doesn't work very well, particularly if you are looking at a plane at an extreme angle. You can still fix the nav problem but you will not be able to quite get back to the view you started with. So I'll be happy if this helps even one person, and if not, it at least gave me something to do on a rainy Friday afternoon...
PS: Also made a new journal skin!
It's been fun~
I disabled my auto renewal for core membership. I'll probably check in a few times a week. I wish all my friends at DA the best of luck. I'll be around, but not very often. You can find me on the Face if you like. https://www.facebook.com/HalTenny/
No Eclipse for me
As of right now, I hate it. And I'm not going to pay for a core membership for something I DON'T LIKE. At the very least I'm dumping my core membership as soon as it runs out, and probably Deviantart altogether. They are catering to viewers that use phones over the members that provide the content. I stuck by the good and bad for almost ten years, but not this time. I don't even care if they never updated the original design again. Just leave it active, don't force something on us we don't want.
GOTG VOL 2 gets Shot at an Oscar
This wouldn't normally be anything to mention here. But having worked as a concept artist on "Guardians of the Galaxy vol 2", I am of course quite interested to see if Guardians 2 can snag an Oscar for visual effects. I am always quick to say that few - if any - of the 300 + concept images I sent to Marvel were used in their raw form in the film. However, a good majority of the eye candy on the planet Ego was based on, inspired or influenced by the images I submitted. Particularly the palace design, bedroom area and most of the subterranean scenes. Other concept artists such as Sam Michlap and Craig Sellars (and many others) were able to tak
Interview in Digital Art Live
I was interviewed a few weeks ago for the August issue of Digital Art Live online magazine. If you would like to read it, I finally got a link to work, I hope. I couldn't link to it directly, so you'll have to click the link on my FB page if you want a look~ https://www.facebook.com/HalTenny/posts/10207546647864772?pnref=story I didn't realize until it came out today that one of my images would be on the cover, "Fantasy Tree Cottage". Below is what the issue cover looks like!
