Hello everyone and welcome to a new (probably short) series of videos I do involving the source code from Valve for Half-Life 2, and some guides on how to do stuff with this code. In this episode, I followup on the Molotov tutorial I did a while back by talking about an issue that has been brought to my attention thanks to @soup1.0. This involves giving the Molotov to an NPC to throw, which crashes the game when they try to throw it! I outline how to make changes to the Molotov code to make it work with NPCs while also discussing a possible improvement that could be made, where NPCs don't even need to have the Molotov as a weapon to be able to throw one! I also go over a couple of miscellaneous fixes regarding fire damage and the Molotov viewmodel. Please let me know what you think and see you for whatever I decide to do next, thanks for watching!

Hello everyone and welcome to a new (probably short) series of videos I do involving the source code from Valve for Half-Life 2, and some guides on how to do stuff with this code. In this episode, I demonstrate how to add Thexa4s PBR shader for the Source engine. Unfortunately, this only seems to be an UnlitGeneric version, plus I cannot tell you how to make textures that make use of this shader, so apologies for this! Please let me know what you think and see you for whatever I decide to do next, thanks for watching!

Hello everyone and welcome to a new (probably short) series of videos I do involving the source code from Valve for Half-Life 2, and some guides on how to do stuff with this code. In this episode, I introduce an alternative method for shader authoring and show how to get into a position to be able to compile custom shaders for your mod by using a modified compiler by SCell555. Please let me know what you think and see you for whatever I decide to do next, thanks for watching!
