# WEIGHT PAINTING TIPS & TRICKS ![Ivory Simple Minimalist Travel Magazine (8)](https://europe1.discourse-cdn.com/krafton/original/2X/e/ebba8e5bd9bf3974d2d6fe024cc2fe88b064adf1.jpeg) Today I’m going to try and help you with the most common Blender Weight Painting _disasters._ ## 💫:custom_heart: **How Do I move around Blender?** You need 3 things only: your mouse wheel and the right shift on your keyboard - **Mouse wheel:** keeping the mouse wheel clicked will allow you to turn around - **Shift:** Shift + Wheel will allow you to move up-down and left-right. - - **Right click:** (while inside Weight Painting Mode) when you are weight painting it will prompt a menu to change the weight and the radius of your mouse/paintbrush Now, some terms and some places you are going to need to click: - **Paint Skin Weights:** Bottom left of the inzoi plugin for blender, this will allow us to “see” the areas and heaviness of the weight painting, and modify them. If you stop seeing the weight or are not able to modify anymore, just **open the inzoi plugin** pannel and **click on it again**. You won’t see the “vertex groups” until you click here. ![Paint Skin Weights](https://europe1.discourse-cdn.com/krafton/original/2X/f/fb95dd34cf8a97fde4bb639a36c60cf9ff546fd0.png) - **Vertex Groups:** You access them by clicking “Data, ObjectData Properties” or the inverted triangle symbol. Here is where the weight has attached, it refers to part of the bodies so we will be clicking throught them to fix the messes. ![vertex groups](https://europe1.discourse-cdn.com/krafton/original/2X/0/031177c5880cd409f399f81c377634f00c60ac79.png) - **Brush:** On the 2nd top line pannel of Blender, you can open the dropdown and choose between: ![brush menu add substract](https://europe1.discourse-cdn.com/krafton/original/2X/d/d2ebab0bb4e8ef5c8a27cc49677fe0a95a6343f5.jpeg) ![Select Substract or add brush](https://europe1.discourse-cdn.com/krafton/original/2X/1/195754061ea6e190844fa637b761564ae1470e77.jpeg) - **Timeline:** This line here, you can move it right and left to move your avatar so you can better see how the clothes behave with the weights assigned. ![image](https://europe1.discourse-cdn.com/krafton/original/2X/8/87c85615e61e1608af5ec9b39070b2834e2cb7f5.png) # 💫 :custom_heart: **Disaster Report: Common _“messes”_ and how to fix them** ### _ **Tiny Tips** _💫 ```auto In order to delete and add weight to an area, try to click the very edge/border/vertex of that area. Also, you can scroll until inside of your zoi and move around from inside if you can’t reach one of those vertex/”pointy parts”. ``` ![image](https://europe1.discourse-cdn.com/krafton/original/2X/3/3de5a066cbc79902498bad5151616eafc76ab686.jpeg) 1. ## **First “Disaster”: _Armpits to the Sky_** How it looks: ![after deleting wrong upper arm weight trust the process](https://europe1.discourse-cdn.com/krafton/original/2X/3/3ead1810a53907d30630961b365ca26310ebb710.jpeg) ![PROBLEM TWIST CORE EXAMPLE 1 (EXTRACT FROM HERE, BICEPS, TRICEPS, TWISTCORE 02 AND ADD TO SPINE 04)](https://europe1.discourse-cdn.com/krafton/original/2X/3/3dc2bda4cda06a81f473aa23c993e125f63c4d12.jpeg) _**Culprits (USUAL SUSPECTS)**_: Specially (and this almost always applies) anyone that is called X\_tistCor\_0x. These are the enemies, to an extent ![UPPERARM](https://europe1.discourse-cdn.com/krafton/original/2X/8/83efdc24cfeaa6285644347dc4fc6cb0af205e09.png) Substract from here: - Upperarm\_twistCor\_01\_l _(or Upperarm\_twistCor\_01\_r for the right side)_ - Upperarm\_twistCor\_02\_l _(or Upperarm\_twistCor\_02\_r for the right side)_ - Upperarm\_tricep\_l _(or Upperarm\_tricep\_r for the right side)_ - Upperarm\_bicep\_l _(or Upperarm\_bicep\_r for the right side)_ Add here: Once you have deleted from the usual suspects, let’s add to both the _ **spine\_04** _ and the _ **spine\_04\_latissimus\_l** _ (or Spine\_04\_latissimus\_r for the other side) **NOTE** : The more weight you add, the redder it it will look, that is perfectly fine. In this case _ **Red** _ is _ **Good** _. ![LATISSIMUS](https://europe1.discourse-cdn.com/krafton/original/2X/0/03eafe4008d049c4192d30f110f24d5246925bc7.png) ![SPINE](https://europe1.discourse-cdn.com/krafton/original/2X/0/06d4d3626de19caf1aadd496295a7d0c67361633.png) Now, it will look more like this: ![UPPERARM FIXED 2](https://europe1.discourse-cdn.com/krafton/original/2X/c/c754f42202170018c1e9b57689a9c99b87ac6e13.jpeg) ![UPPERARM FIXED](https://europe1.discourse-cdn.com/krafton/original/2X/4/4cf2905c2a9e8aab09cbfd4694ff7224bdbcfd0a.jpeg) 1. ## **Second “Disaster”: _Reaching Fingers_** How it looks ![THUMB ISSUE](https://europe1.discourse-cdn.com/krafton/original/2X/c/c26eaae47d663ccbf08d5b6e936ea1a11882f3fd.jpeg) _**Culprits (USUAL SUSPECTS):**_ The ever-troublesome _ **thumb\_01\_l** _ or _ **thumb\_01\_r** _ ![THUMB 01 AS ALWAYS](https://europe1.discourse-cdn.com/krafton/original/2X/6/673ea219ce9d668618c78831f4d74ef44346d1e8.png) Substract from here: - _ **thumb\_01\_l** _ (or _ **thumb\_01\_r** for the right side_\*)\*\*\* Add here: - _ **Wrist\_inner\_l** _ _(or **wrist\_inner\_r** for the right side)_ Now, it will look more like this: ![after substracting thumb weight](https://europe1.discourse-cdn.com/krafton/original/2X/d/d6599160909433d1ef08fdd73ba0916b7cf4a49a.jpeg) 1. ## **Third “Disaster”: _Crossroads Crotch_** How it looks ![CROTCH COMMON BAD](https://europe1.discourse-cdn.com/krafton/original/2X/5/5925a812d143d652e181e4e08bfb67e686c65272.jpeg) _**Culprits (USUAL SUSPECTS):**_ _ **Thigh\_twistCor\_01\_l** (or **Thigh\_twistCor\_01\_r** for the right side)_ _ **Thigh\_twistCor\_02\_l** (or **Thigh\_twistCor\_02\_r** for the right side)_ _ **thigh\_in\_l** (or **thigh\_in\_r** for the right side)_ ![TIGHT TWIST COR THE MOST IMPORTANT](https://europe1.discourse-cdn.com/krafton/original/2X/2/251864be11152465df798e43898fc7055bfa4e0d.png) ![TIGHT VERTEX](https://europe1.discourse-cdn.com/krafton/original/2X/c/c9632397cfb0725d05040e36828024c69389f781.png) In this case, you will have to substract from the vertex above and add to the same in this manner: - To “fix” the right side substract from the left side _ **Thigh\_twistCor\_01 / Thigh\_twistCor\_02 & thigh\_in\_l and add to the Thigh\_twistCor\_01\_r / Thigh\_twistCor\_02\_r & thigh\_in\_r vertex groups.** _ - To “fix” the left side substract from the right side _ **Thigh\_twistCor\_01\_r / Thigh\_twistCor\_02\_r & thigh\_in\_r and add to the Thigh\_twistCor\_01 / Thigh\_twistCor\_02 & thigh\_in\_l vertex groups.** _ ## Last: _ **WHY DO MY DRESSES BREAK?** _ The most common problem when creating dresses and skirt for our zois is that once the zoi starts moving, the dress inevitably breaks in two. If this happens: _don’t despair!_ Your weight painting looks like this? ![HARSH LINES](https://europe1.discourse-cdn.com/krafton/original/2X/3/36f6fd0b47affda27688bbd1e3dad0a13b8c8003.jpeg) That is the issue here! Avoid harsh lines at all cost by slightly painting weight in each vertex of one side towards the other side, till they look somewhat like this: ![HARSH LINES how it should look](https://europe1.discourse-cdn.com/krafton/original/2X/a/aa09bf81e359ba94c32132a712b70cb8ed07f61c.jpeg) Using the “smooth weights” too on the top left of Blender can also help, but be very careful because sometimes it can create openings in your dress’ seams. _ **And most importantly:** _ . ![MODkit Thumbnails (34)](https://europe1.discourse-cdn.com/krafton/original/2X/0/0065122f1a50118fc9654b981e7a1800f8c72447.jpeg)
