[@sufianmaroni378]

LOVE IT. Appreciate how you show it. Its hard for me T_T so many tutorials and you are one of the many help much to get my visual right :) Thank you. I feel like crying sometimes....... suddenly my emitter just won't give the same result as yesterday. spark ar is so fragile and i gave up........

Your tutorials are INCREDIBLE. And I'm sorry to add to the comments like this.. BUT can the different images from your sequence be populated at random? So they are all different at birthrate?

[@CatalystChannel]

Yes, you could adopt a similiar setup as what was used in the What am I style filter tutorials and adjust birthrate via runtime and an offset with a checker (e.g. greater than). Hope this makes some sense... its late :)

[@robertsweeney2]

@@CatalystChannel You are wise beyond your years, going to be a fun night for me. :)

[@ITGeneral]

lit vid! one question: I'm in the making of a 'who / what are you filter' - is it possible to use the resulting picture that is displayed above the face simultaneously as a particle? (for example: when there's a heart displayed above the face, can the same heart also be shown as a particle in the background at the same time?)

[@CatalystChannel]

Yes, simply use the same material as used for the randomiser as the material for particle and it will show the result as particle. Ideally set as a .png with alpha test

Hi, thanks a lot for your video! I've been having a problem, I don't want to control my particles, however I see that they each one is changing, is it possible to randomly create new ones but make sure that they don't change until they're out of the filter?

[@milesjambeau3241]

You could just create a new generator for each particle type and set the speed very low for each one therefore making to illusion of having one generator making random ones ? I'm new to spark at but I thinking that should work

[@AimeeKatherine]

Thank you!

[@krissie2454]

Hello! Super helfpul tutorial. I added a rectangle with a frame type of graphic on the filter and the particles work fine on Spark AR. however, when I test this on my phone, the particles disappear. Would you know how to work around this?

This is great - please, could you add an update for how to add these floating particles behind your quiz game tutorial (what snack am i?) We'd love to combine them, but right now these additions mean the cards on the head don't appear consistently

[@CatalystChannel]

This video really needs reexploring, its one of the earlier channel vids and honestly think could do better. I will try and get this recorded and addressed over the weekend for Monday as its a video that could solve multiple requests I get especially on particles and layer orders e.t.c

[@felifyavuz9437]

Thank you for a great tutorial :). I have a problem, when I move the particles at the bottom of the camera, they suddenly appear in front of the user. I can not make them exist behind the user. I did exactly what you did, but when I changed the "user" material's diffuse texture to cameratexture, the console popped up and gave this error "Unset shader uniforms: u_Texture1". What should I do to fix this?

[@CatalystChannel]

This could be either down to texture file not being found, not uniformed or shader type problem. In regards to order ensure layers are correctly set for each object

[@stefano1891]

Same problem

[@haydendoward5714]

I got the same console error the first time but not the second time. To make the particles go behind the user I had to uncheck the 'Use depth test' and 'Write to depth buffer' options under Advanced Render Options for the particle material (should be fine without them if using layers like this), also changed the Shader Type to 'Flat', try give that a go :)

[@Hayabusaturbooo]

Hey Catalyst, I am also new to SparkAR and i am currently just playing around and watching tutorials. But one thing is not working for me as it is in the tutorial. When i add a Particles System Layer, the particles are already blacked out and are not the usual default black and white texture. If i want to add a material to them - they disappear completely. Can u help me?

[@CatalystChannel]

This sounds odd and should not happen, only reasons I can think of are either a) Render layer settings b) Lighting issue c) Some weird glitch. Could you send a picture of the setup and issue to [e-mail] and will aim to answer before end of the week

[@Hayabusaturbooo]

Hi there! Nice to now ur channel... I'm Niezken from Indonesia. I have a question here... I have a project that got me confused. I had 3 layer on the project. 1st for a background (animated), 2nd for the person, and the last one is plane item that attached with facetracker (in front of eyes). It looks great until i found a bug. When the "person" move too far from the camera (still detected), the plane object is disappear. It move across the "canvas" and disappear. Is it any way to solve this?

[@jasaeditfotoonline1950]

Hello, can you Solve this please... Your Effects May Not Be Seen or Functional on Some Devices Your effect contains capabilities that are not supported by the following devices: segmentation. Unnecessary capabilities can be removed in Spark AR Studio.

How do I put 3 icons all together?

[@ventoPS]

Hey! Ive been playing around with this effect as well, was wondering, can you make it so that it interchanges the pngs randomly? So - in your example - that it would put heart eye emojis and smiley emojis at the same time? So that some of them are heart eyes and some of them are smiles. Or can you only put one png in the animation, that you change by tapping? Thanks for the great tutorial, hope this makes sense :)

[@CatalystChannel]

Emitters (particle systems) can only be assigned one material per emitter. You can change the material via using animation sequences and frame transitions to progress the frame (material texture).

[@ThePixelitomedia]

how to make the particle bigger? I use a logo as particle but its tiny even if logo is 1024x1024 px

Hi, Your lessons are really amazing! I faced with the problem when I want to combine background and face retouching. I created 2 rectangles, one for background and another for user (Diffuse -> cameraTexture; Alpha -> personSegmentation) Then I've added 2 faceMeshes: one for face copy and another for retouching. But when I create a face copy material I get this "white boundaries" effect around the face in some cases. Basically it depends on the angle of face. Here is an example: ibb.co/J5rBLxd Do you know how to fix it?

Hi! nice video. I have a problem with some 2d objets. When the person gets too far from the camera the objets disappear. And when I am on a closer distance appear again. Do you know how can i fix this? THanks!

[@CatalystChannel]

This will be to do with Z depth, if possible you can disable deoth test on materials advanced render options this ignores z depth (clipping) but be warned it can also cause ither issues if layer orders are not right. Try toggling it off see what happens

Keeping image sizes small (canvas size) and optimising where possible is key. Under edit properties you can adjust compression amount, changes wont take into account until saved. Spark closed and reopened
