Fantastic Park // WIP

Hi !

My dragon is almost done so I'm working on the next step, "his toy".

My goal is to make a diorama, inspired by "Jurassic park", where a dragon attacks a tourist bus. Actually, in my "Fantastic park", there are no dinosaurs, but magical creatures like mermaids, chimeras, griffins, unicorns... dragons !!
And yes.... They escape !

Please notice that the story haven't to be original, it's just a guideline to help me to keep motivated in doing it. I just want to fill my portfollio with exiting stuffs but nothing is intended for sale !

The tourist bus constantly covers the big island roads in order to spread the tourists in numerous spots.
I chose to make a city bus to easy getting on and off. It will wear the park's colors.

I show you my dragon's eye at the same time.

Your project reminds me the The Abandoned Land of Disney's Animal Kingdom : Beatly Kingdom
Check this. It can bring you some inspiration !

Keep up the good work !

Hey @romainrevert, thank you for your message. Very interesting !! I didn'nt knew Beastly Kingdom and that was cool to discover this.

The funny thing about it is that its logo looks a lot like the first idea I had for Fantastic Park's one. My goal is to make a clear tribute to Jurassic Park, so to put a dragon instead of the T-Rex was obvious ! ^^. But my decision isn't took for now, I'm still thinking about the logo who will be drawn on the bus ! ^^

Hi !
Here is the continuation of the project !
This version supports the tesselation; I will now create the low poly version.

Your opinion is more than welcome !

New step in my project, the low poly version... I have some questions :slight_smile:

1/ Is it possible to suppress all the little overlay bugs from the windows. To improve the sorting, I put each glass in a different object, but it's not enough. Bugs are still visible from different angles.

2/ Why the Windshield seems to be fragmented (More visible from the inside)

3/ The SD/HD toggle isn't here... I don't know why. Here, I have eight 4096² + eight 2048² textures. I tried to assemble the eight 2048² maps in two 4096² ones with another UV Channels in order to reduce the maps number. No success ! : The SD/HD toggle appears then, but while HD version is pretty, SD one is all blured. Any clues to understand this ?

4/ Why some meshes were exported in triangles by 3DS Max while others keep quads ? Every mesh is an "editable poly" which was "reset XForm-ed" before the export.

Any comment is welcome ! Thank you :grin:

Just for fun, it's a test. The final project will not be animated ! ^^

It's called Zfighting, sadly in certain angles it's just not really possible. Sometimes it just doesn't want to the way it should :stuck_out_tongue:

could be your vertex normals that are a bit out of control there.

So not exactly sure, what you could have done is put a lot of repeating uv's overlapping especially since you don't seem to have an ao map :slight_smile:

do you export via exporter or as obj/fbx? there might be some settings that affect that somewhere :slight_smile:

Overall i think you have a cool project that could be a bit better optimized in certain areas (for example using a plane for repeating textures, saving space that way, the modeling looks very clean on the other hand. I guess the final texture res and co will depend on what you plan to fill your scene with. I did 3 very big scenes before with vastly different outcomes. Less Vram = faster load speed

One where the textures needed to be high to not look bad didn't do to much preplaning on there.

Vram - 4GiB / 82 Textures / 15 Materials/ 50431 Vertices

One that i did plan out before and put multiple things on the same materials and looked that nothing is higher than it needs to be

Vram - 1GiB / 100 Textures / 18 Materials / 55412 Vertices (more of them were lower res)

My first one, therefore the "worst" didn't do much planing and in a lot of areas did waste quite a bit of polys and materials that could have been combined :wink:

Vram - 7GiB / 236 Textures / 58 Materials / Vertices 552465

Maybe those give you a bit of insight in how to plan for your final scene :slight_smile:

Thank you so much @dark_minaz !

1/ Too sad :disappointed_relieved:, I hope that in the final project, that will be cool...
2/ I don't think so... Or there are something I don't get about vertex normals.
3/ I think I will bake the AO in the final piece... I'm not sure to understand everything about texture optimisation on sketchfab... Is it better to have numerous little maps or a few big ones ? I will do tests...
4/ I make a FBX, but I believe all the meshes have identical parameters... So why I obtain a variable aspect ?... Mystere!

Thank you for your scenes ! I will think about ! That's my very first "big scene" but I give it a lot of time... I hope it will be clean enough at the end. Good job for yours, I like your batman stormtrooper ^^, very funny and "match-up" like my project! :slight_smile:

autodesk sure got a funny way of doing magical things sometimes
maya currently adds vertexes when i mirror (sometimes) really odd but as long as you know how to counter the bugs it's not a big issue :slight_smile:

to 3, if you add an ao you need a non overlapping uv (or atleast a uv map for the ao, you can have mutliple) for the texture you can simply use overlapping ones for all the chairs for example. Would save a bit of space / looks better even in lower res

for sketchfab it's better to have fewer slightly bigger textures. The lower the vram the better. especially for phones and older pc's, most newer ones you can go pretty heavy on, as you can see on my first scene that got 5mio verts and 236 textures :stuck_out_tongue:

you can also just upload it, see the vram and then check where you could lower it from 4k to 2k for example :slight_smile: that is how i did it on my mad labs scene, testing between 4k,2k,1k,512 at what point it looks to bad and where you can still say "good enough" :slight_smile:

looking forward to your next steps, really interesting to see mixups between multiple movies/ideas. Quite a big fan of those (kinda why i made 4 models doing that already^^)


(Yannick Deharo) #33

I spotted the Cerebro door in the lab too ^^.

I already made tests with a different UV for chairs, but I realised that the difference was too slight to permit me to pass from 4096px to 2048px maps...

I noticed also that if normals maps works fine on Unity with overlapping UVs, it's not the case on Sketchfab where symmetry reverse the effect . So, I decided to do without overlapping!

Right now, for the bus I have 4096px maps for Diffuse and Normals, and 2048px ones for the rest (Opacity, Metalness, Roughtness, Emissive, when it's necessary).... But it's already too heavy for mobile (or this is the transparence algorithm...). My optimisation work isn't fully achieved yet! ^^ :sweat:

Little step to share my progress with you ! ^^



(Yannick Deharo) #35

Hello !

Just a message to inform you that the project is still on track. With time, I created three characters, the hills, the bridge and a few plants. Also, I discovered some powerful tools.

The scene isn’t totally ready to be shown on real time. Now I have to add details and to bake the occlusion because I’m not totally fond of the Sketchfab’s. I’m pretty happy for the moment.

My draft model is displayed in SD by default, I have to select “HD” to see an “unblurred” result. so I have a question :
Is it because of the weight of the maps (which I can reduce with the JPG settings from Photoshop), or because of their count or resolution ? Wich is the most likely case ? Without the answer I will make a lot of different tests to find the solution, so if you have an idea, don’t hesitate to share it with me ! Thank you ! :slight_smile:
